Game: Diablo IV (PC) – Patch 2.0 / Season 4
Issue:
When Fireball reaches skill rank 40 or more (through item bonuses), the burn damage effect from its enhanced node disappears. The tooltip shows “0 [0%] burn damage over 6 sec” and no DoT effect is applied during combat.
Reproduction steps:
- Equip gloves, staff, and/or ring that give +skill to Fireball, raising its rank to 40+.
- Open tooltip – observe that burn damage is 0 [0%].
- Enter combat – enemies take no burn damage.
- Remove one item to lower Fireball rank below 40 → burn damage returns.
Conclusion:
This bug significantly weakens Fireball builds focused on burn DoT and only affects high-end characters with good gear. Please fix this skill rank overflow issue.
Tested on:
- Staff: +16 to Fireball
- Gloves: +8 to Fireball
- Ring: +7 to Core Skills
- Tooltip confirms exact change between rank 39 and 40.
