![]() | Shieldburst | Solar | T | 3 | ||||
![]() | Controlled Demolition | Void | T | 2 | Void ability damage and volatile explosions apply volatileVolatile explosions restore 90 HP to allies within 40m of user | probably the strongest sustained chunk healing in the game | 3 | S |
![]() | Winter's Shroud | Stasis | H | 2 | 60 slow stacks to enemies within 9m for 8-12s on dodge+300% class regen for 3s on slow50% DR for 4s on dodge | essentially permanent 50% DR and free Courage application on a non-boss scale | 4 | S |

![]() | Ascension | Arc | H | 3(2) | Airborne air move consumes class ability (triggers effects) and amplifies allies and jolts enemies within 10m | 100% teamwide Amplified uptime while triggering class ability effects | 6 | S |
![]() | Sol Invictus | Solar | T | 2 | Solar ability kills, scorched kills, and Hammer of Sol impacts make refreshable Sunspots for 12sRestoration x1 for 5-7.5s, 100% grenade/melee regen inside | constant Restoration access, chainable staggering ticks on adds, passive ability regen | 7 | S |

![]() | Weavewalk | Strand | W | 2 | Air move toggles Weavewalk while airborne, giving 90% DR, perched Threadling every 0.5s, costs 25% melee per second, and disables weapons, abilities, etc., Woven Mail to allies on exit (2-20s) | excellent response strategy for survivability in low power content | 9 | A |
![]() | Consecration | Solar | T | 3(2) | Sliding powered melee creates igniting slam on recast25% non-melee DR during animation | has strong intangibles but doesn't have any outstanding special effects | 10 | A |
![]() | Stylish Executioner | Void | H | 2 | Debuffed kills give invisibility (8-11.2s) and truesight (4s), with invisibility going on cooldown for 2s after wearing offMelees deal +300% damage, weaken for 5s, have more range | invisibility not as high value any more, melee damage bonus is situational | 11 | A |
![]() | Threaded Specter | Strand | H | 3 | Spawns strand decoy on dodge that attracts attacks, lasts 12s, and explodes and spawns 2 Threadlings on destruction0.6x class regen while equipped | high uptime and deaggro source, very easy to use | 12 | A |
![]() | On Your Mark | Solar | H | 3 | 10 stack buff in 15m for 12s (crit kill/HC crit: 2, dodge: 1, crit: 1)15-45? reload, 5-50 Weapons, 0.95x-0.85x? reload durationCure on kill at 10 stacks | high utility for fireteam damage, provides pseudo-Devour effect | 13 | A |
![]() | Gunpowder Gamble | Solar | H | 2(3) | 6 stack explosive with 6s ICD that replaces grenade (weapon: 1, ignition/scorch: 3, ability: 4, super: 6)Bigger ignition + submunitions if shot, otherwise detonates 3s after throw | splash damage outlier even though doesn't provide much consistency | 14 | A |
![]() | Storm's Keep | Arc | T | 2 | Bolt Charge x4 to allies on class ability cast (x6 for thruster)Barricade gives Bolt Charge (no Frequency doubling) over time and allows for weapon discharge at max stacks | free fireteam damage, but very one-dimensional use case | 15 | A |
![]() | Into the Fray | Strand | T | 2 | 3 pulses that give Woven Mail and 15 HP on Tangle destructionWoven Mail to allies on super cast+300% melee regen during Woven Mail | solid survivability with 10s Woven Mail source, great uptime from melee regen | 16 | A |
![]() | Lethal Current | Arc | H | 2 | Melee hits on jolted enemies apply blindJolting 7m range aftershock melees, double damage light attack on Arc Staff after dodge | Blind application generally not relevant, aftershock damage just okay | 17 | A |
![]() | Lightning Surge | Arc | W | 2 | Sliding jolting powered melee that grants hit-based Bolt Charge and Amplified, gives %DR for ?s on usage | straightforward splash melee aspect, more risky and less consistent vs. Consecration | 18 | B |
![]() | Roaring Flames | Solar | T | 2 | 3 stack buff for 20s (ability kills and ignitions)20-73% non-melee ability damage (67-200% melee)Unpowered conversion and 30-40 scorch on melee | strong ability damage buff and forgiving timer but not very versatile | 19 | B |
![]() | Touch of Flame | Solar | W | 2 | Firebolt gets 50% radius and 5 enemies, solar gets 2s duration and magma blobs, fusion gets 2 explosions, and healing gets Cure x2 and Restoration x2 for 4-6s | like Touch of Thunder, damage/Restoration x2 specialist but not as applicable | 20 | B |
![]() | Touch of Thunder | Arc | T | 2 | Flashbang blinds after first bounce, lightning has 2 charges and jolts on every tick past 1st, pulses make Ionic Traces every 1s and ramp damage, storms roam after detonation | meta for grenade damage, but zero survivability or utility outside buffing grenades | 21 | B |
![]() | Mindspun Invocation | Strand | W | 2 | Grapple melee makes 3 Threadlings, Threadling consume makes 5 perched Threadlings, shackle consume gives Weaver's Trance for 25s (suspending explosion on kills) | best combination of suspend CC with offense, technically best Threadling spam | 22 | B |
![]() | Iceflare Bolts | Stasis | W | 2 | Freezing 12m seeker on enemy shatter8s ICD after 7 seekers | insane chain CC spread, not very offensive but great ability efficiency, build-dependent | 23 | B |
![]() | Whirling Maelstrom | Strand | H | 2 | Spawns tracking vortex upon Tangle destructionVortex unravels targets on kill, triggering Tangle effectsCan be grappled to | pretty solid splash with lingering stagger effects, also QoL with grapple point | 24 | B |
![]() | Hellion | Solar | W | 2 | Class ability spawns solar turret for 20s3 shot ignition with Ashes, 4 without (no grenade scaling) | high uptime stagger source that takes low CD ability instead of grenade/melee | 25 | B |
![]() | Bleak Watcher | Stasis | W | 2 | Grenade cooldown changed to glacierCharged grenade deploys stasis turretTurret applies 20 slow on hit and lasts 25-30s | reliable CC option, helps "soften" targets in the way Hellion does | 26 | B |
![]() | Weaver's Call | Strand | W | 2 | 3 Threadlings and perched deployment on class ability castDamage/kill counter that adds perched Threadlings with 2s ICD10% class energy on Threadling hit | passive damage and class regen, very background | 27 | B |
![]() | Flechette Storm | Strand | T | 2 | Sliding powered melee knocks enemies away, consumes 50% per cast, and launches barrages of unraveling projectiles25% DR against non-melee during animation | ranged but definitely lacking in power compared to other powered melee aspects | 28 | B |
![]() | Ionic Sentry | Arc | W | 2 | 6 stack 15s turret with 6s ICD that replaces grenade (weapon: 1, ability: 2), blinding on impact and chaining lightning at enemies within 16m, granting Bolt Charge stacks on hit | like Bleak Watcher but does damage and synergizes with Arc sandbox | 29 | B |
![]() | Diamond Lance | Stasis | T | 3 | Spawns 7s ICD lance on stasis or ability killLance can be thrown or slammed, freezing and giving x2 Frost Armor to allies on impact (slam only) | gameplay loop is too slow and non-lethal, but decent Frost Armor source | 30 | B |
![]() | Unbreakable | Void | T | 2 | Charged grenade makes blinding void shield for 3s with 95% DR, releases response damage upon depletion, makes orbs every 4.5s every 10 damage taken on Sentinel Shield | best get-out-of-jail card in the game, but tied to long CD | 31 | B |
![]() | Vanishing Step | Void | H | 2 | Dodge animation travels further and gives invisibility for 5-7s | shorter invisibility CD vs. Trapper's with better synergies | 32 | B |
![]() | Ensnaring Slam | Strand | H | 2 | Suspending dive air move, triggers class ability usage effectsWoven Mail for 4s for each suspended enemy, up to 20s | very consistent Woven Mail source, suspend not as relevant in current sandbox | 33 | C |
![]() | Tectonic Harvest | Stasis | T | 2 | Small Stasis Shard on crystal or enemy shatterx1-3 Frost Armor and 10-? HP from shard pickup | best of the harvest aspects, but still forces shard gameplay loop | 34 | C |
![]() | Arc Soul | Arc | W | 2 | Rifts grant allies Arc Souls+40-120% class regen near allies (up to 3)Amplified boosts Arc Soul fire rate by 2.25x | overshadowed by Getaway Artist and damage benefit isn't substantial in full teams | 35 | C |
![]() | Bastion | Void | T | 2 | 45 HP Void Overshield to allies on super cast or barricade castBarricades regen 11 Void Overshield HP/s | best teamwide Void Overshield applicator, but tied to long CD | 36 | C |
![]() | Knock 'em Down | Solar | H | 2 | Powered melee kills refund if RadiantMarksman Golden Gun is 4s longer, Deadshot Golden Gun gets 15% DR, Blade Barrage gains 3 knives per fan | refunds a variety of melees that aren't very potent | 37 | C |
![]() | Electrostatic Mind | Arc | W | 2 | Ionic Trace on Arc ability and Arc debuffed killsIonic Traces grant Amplified | good elemental pickup but doesn't affect endgame outside spammability | 38 | C |
![]() | Widow's Silk | Strand | H | 2 | Grants additional grenade chargeGrapples make grapple points that grant allies grapple ability | consistency pick for Cyrt synergy and grapple point creation | 39 | C |
![]() | Grim Harvest | Stasis | H | 3 | Stasis debuffed kills spawn Stasis Shard (size based on rank)x1-3 Frost Armor and 10-? HP from shard pickup | core shard spam aspect, but shard gameplay loop isn't very endgame-appealing | 40 | C |
![]() | Howl of the Storm | Stasis | T | 2 | Additional melee chargeSliding powered melee creates 8 crystal wave uppercut | much worse individually vs. better powered melee aspects, needs Tectonic pairing | 41 | C |
![]() | Chaos Accelerant | Void | W | 2 | Overcharge grenades: axions: +2 seekers and 25% damage, scatter: +4 projectiles, tracking, 25% damage, vortex: 7.5% duration, 70% radius, enhanced pull, others: creates volatile HHSN blast | overcharge tradeoff + lack of class-leading options for damage and other purposes | 42 | C |
![]() | Trapper's Ambush | Void | H | 2 | Grants a weakening invisibility dive that uses melee chargeDive leaves smoke cloud that weakens and damagesSnare bomb gives invisibility to allies for 5-7s | not really relevant any more outside of pure stealth scenarios | 43 | C |
![]() | Child of the Old Gods | Void | W | 2 | Deployable weakening Void Soul for 25s on rift castHealing or empowering drain give 4% grenade/melee or 25 HP every 1.4s, and drained kills give 10-50% class | solid debuff extension but more fruitful ability regen options exist | 44 | C |
![]() | Heat Rises | Solar | W | 2 | Weapon and abilities can be used while gliding20-50% melee from airborne killsCure x2 for allies on consumption, 5-15s duration on aerial kill | good for movement and QoL for in-air shooting, dated Restoration x2 source | 45 | C |
![]() | Offensive Bulwark | Void | T | 2 | 2 throws in Sentinel Shield, unpowered conversion that gives 10 HP Void Overshield, +400% grenade regen, +160% melee damage, 5.5m lunge with Void Overshield active | consistency problems in low power content, effects comparable to better uptime aspects | 46 | C |
![]() | Shatterdive | Stasis | H | 2 | Grants 4s ICD vertical dive that shatters crystals and enemiesIncreased shatter damageFrost Armor on crystal or enemy shatter | QoL Frost Armor source, but still mostly just a movement option | 47 | C |
![]() | Touch of Winter | Stasis | H | 2 | Coldsnap seekers duplicate on freeze and spawn crystals on chain detonations, duskfield gets 50% radius and crystal inside, glacier becomes a heptagon | extremely one-dimensional aspect, effect is quite niche | 48 | C |
![]() | On the Prowl | Void | H | 3 | Entering invisibility marks a random non-boss targetKilling target creates ally-cloaking weakening smoke cloud and gives reload and ability energy (3 stacks, 7s) | spree requirement too strict for endgame, walking to smoke clouds also potentially risky | 49 | C |
![]() | Flow State | Arc | H | 2 | Amplified on jolted enemy kill+200% class regen, +50 reload, 0.8x reload duration, and 66% DR during dodge while Amplified | QoL effects but Amplified trigger and dodge DR not very applicable | 50 | C |
![]() | Icarus Dash | Solar | W | 2 | Grants horizontal dash with 4s ICDTwo dashes with Heat RisesCure x1 on standard 3 kill counter within 5s | QoL movement choice with physics immunity frames, consistency pick | 51 | C |
![]() | Glacial Harvest | Stasis | W | 2 | Stasis Shard near enemy on freeze (scales with enemy type)x1-3 Frost Armor and 10-? HP from shard pickup | least consistent harvest aspect | 52 | C |
![]() | Drengr's Lash | Strand | T | 2 | Tracking 30m suspending lash on barricade cast | suspend focus on long CD, also mediocre value without Abeyant | 53 | D |
![]() | Juggernaut | Arc | T | 2 | 50 HP overshield (Amplified 33% DR, 60% splash DR, 10% general DR) that gives Bolt Charge per hit absorbed while sprinting with full class energy, fully depletes class on destruction | fairly tanky overshield but uptime too poor and sprint requirement annoying | 54 | D |
![]() | The Wanderer | Strand | W | 2 | Suspending blast on Tangle destructionTangles are unaffected by Gravity and seek/attach to enemiesThreadling kills spawn Tangles | tradeoffs against normal tangle (delayed detonation) and suspend on long CD | 55 | D |
