Self-sustaining HP Burn engine: A3 burns all enemies at 75% and gives the team 50% Inc ACC, refunding 20% of his own Turn Meter per burn placed (10% per burn RESISTED); A1 re-fires on its own 50% of the time whenever a burn activates and carries 75% 60% Dec DEF; A2 ignores Unkillable AND Shield. Passive heals him 20% MAX HP per burn activation, True-Fears anything whose burn expires, and delays his own death once per 4 turns. 28% ATK aura in ALL battles.

THE ARGONITE. This faction was the last one on the account stuck below five bodies — he completes the crypt and closes the Arbiter gate. Separately he is the roster's THIRD AoE HP Burn source behind Searsha and Crypt-King Graal, which is the mechanic Frost Spider (she revives if she dies un-burned) and Spider both run on. HH 10/10 Spider, 9/10 Ice Golem. | 6★ BUILT as of 2026-08-26 (Ice Golem audit) and REMOVED FROM THE 6★ BUILD QUEUE 2026-09-01 — he previously sat at queue #6. Two records were still treating him as an unbuilt build target: the SPIDER team, whose central lever read 'the only owned 6★ with any HP Burn is Geomancer, and his is single-target', which meant its Team Now was built around a constraint that had already expired — he now holds a live Spider seat, replacing Suzerain Katonn, and the burn engine (that dungeon's win condition) is fieldable today; and the FW ARGONITES crypt, whose build order opened with him. HellHades publishes no FW-role ratings for him, only fw_primary — his curated fwRoles are kit inferences, not a source disagreement.

StatsACC › C.RATE › ATK% › C.DMG › SPD
BuildACC is not just a debuff stat for him — it is his turn economy. Pyrenei Power refunds 20% of his Turn Meter per HP Burn PLACED and only 10% per burn RESISTED, so on a full wave the difference between landing five burns and landing three is roughly a free turn. That is why accuracy leads even ahead of crit here. Second: HP Burn ticks off the enemy's MAX HP, so the burn half of his damage ignores his ATK entirely — his gear scales the direct hits (A1 1.8×2, A2 2.8×2, A3 4.5) and the engine around them, not the ticks. Third, his passive heals him 20% of HIS OWN MAX HP every time a burn activates, so HP% on the ring is real sustain that scales with the number of burning enemies, not a dead stat. Set order in practice: run Accuracy (4) + Perception (2) while ACC is short — the TM refund makes accuracy compound — then move to Savage (4) + Perception (2) once substats carry the wall. Relentless is the alternative 4-set if you want maximum burn applications rather than bigger hits.

Appears in

Dragon's Lair
SwapNEW Legendary — HH 8/10: AoE HP Burn is a second DoT line alongside the poison core (burns are not poison, so Blight-style poison blocks and the 10-debuff cap pressure both treat them separately), and his A2 ignores Shield and Unkillable for the purple-bar check.
To-do
Spider's Den
AoE burn engine + team Inc ACC + Dec DEF6★ — SWAP from Suzerain Katonn (audit 2026-09-01), and the swap exists because this record's binding constraint expired: KEBERON WAS BUMPED TO 6★ ON 2026-08-26 in the Ice Golem audit, after the 2026-08-14 Spider audit declared that 'the only owned 6★ with any HP Burn is Geomancer, and his is single-target'. THE BURN ENGINE — this dungeon's actual win condition — IS NOW FIELDABLE. A3 Pyrenei Power burns ALL enemies at 75%, grants every ally 50% Increase ACC BEFORE it attacks (the 225 stage-20 wall, the job the levers had assigned him only in the Ideal comp), and refunds him 20% Turn Meter per burn placed / 10% per burn resisted. A1 re-fires itself 50% of the time whenever a burn activates and carries a 75% chance of 60% Decrease DEF. His passive heals him 20% of MAX HP every time a burn activates on an enemy — against ten burning lings that is continuous, and MAX-HP-based, so Skavag's 35% damage-healing tax misses it. WHY KATONN COMES OUT: his seat rested on 60% Dec DEF + Weaken feeding a HIT-damage plan that only existed because no 6★ could run burns — and Keberon lands the same 60% Dec DEF at 75% against Katonn's unbooked 45% coin flip. This also retires the 'cheapest available upgrade' note: ~3 Legendary tomes into Katonn's A2 are no longer the best use of them. AFFINITY COST: Keberon is Force like the other four seats, so the Morrigaine (Magic) swap on the Spirit stages 20 and 24 matters more, not less. Fresh HH 10/10 Spider. Aura +28% Ally ATK in all battles.
Spider's Den
SwapSEATED IN TEAM NOW (audit 2026-09-01) — see his slot. 6★ BUILT as of 2026-08-26; the record previously carried him at 5★, queue #6, as the highest-impact promotion for this dungeon. That promotion has happened, he has left the build queue, and he took Suzerain Katonn's seat. HH 10/10 Spider — tied for the highest score on the roster.
To-do
Ice Golem's Peak
SwapNOW 6★ (2026-08-26) — and the burn lynchpin that makes the Hard Mode alt FIELDABLE for the first time. HH 9/10 Ice Golem normal AND 9/10 hard; Ayumi 5★ normal / 4★ hard (kit verified this audit). A3 Pyrenei Power: AoE with 75% chance of 2-turn HP Burn on all enemies + 50% Inc ACC on all allies + 20% TM per burn placed. A1 is 2 hits with a 75% chance of 60% Dec DEF, and re-fires (50% chance, once per turn) whenever an enemy's HP Burn activates; passive heals him 20% MAX HP per burn activation and places True Fear when a burn expires. Nothing on his kit is Counterattack. CAVEAT vs the old note: his damage is NOT purely ticks — the A1 re-fire is a direct 2-hit attack, so threshold discipline applies. In NORMAL mode he lost the burn seat to Geomancer on aura + Stoneguard (HH tie 9/10); first man off the bench there.
To-do
Hydra
SwapNEW Legendary — HH 8/10 Hydra: HP Burn deals DOUBLE to the Blight head and ticks through Serpent's Will on a regrown head, and his A2 ignoring Unkillable/Shield answers heads hiding behind them. His A3's team 50% Inc ACC pays the Suffering +50 RES surcharge that Ostrox currently covers.
To-do
Doom Tower
SwapNEW Legendary — Ayumilove 5★ DT Floors and 5★ FROST SPIDER, which is the one that matters: she revives at 50% with full TM if she dies un-burned, and this account's burn uptime was previously a Geomancer coin flip plus Searsha. Keberon is a third source at 75% AoE, and his A3's team 50% Inc ACC helps pay the 330 ACC Hard tax for everyone else.
