Platform/Build: PC (Steam). Weapon/Perk: Wolfsbane (Exotic axe) + Burning Ambition Refit catalyst. Expected: Burning Ambition adds Scorch from sustained damage; hits to an already-Scorched target continue to build Scorch. Heavy attacks should follow the same Scorch rules as light attacks. Actual: Outside Overclock mode, heavy attacks never apply Scorch and do not increase existing Scorch stacks. In Overclock, heavy attacks do cause/advance Scorch as expected. Repro Steps: Equip Wolfsbane with Burning Ambition Refit (no Overclock active). Hit a single target with repeated heavy attacks → observe no Scorch applied. Apply initial Scorch via light attacks (you’ll see ticks once Scorch is present), then switch to heavy → Scorch still does not advance. Activate Overclock and repeat Step 2 → heavy attacks now apply/advance Scorch. Reproduced on red bars, majors, and bosses; reproduced in shooting range. Notes/Controls: • Different armor mods/aspects disabled to rule out interactions. • Behavior persists across instances and relaunches. • Burning Ambition on other weapons is known to add Scorch after “direct hits”/sustained damage; here heavy may not be flagged as eligible when not Overclocked. Impact: Lowers Burning Ambition’s utility vs champions/bosses when using intended heavy-attack windows; Overclock-only consistency suggests a flagging/state bug.
