Inferno Core

Kills explode for 2% of the slain enemy's max HP, hitting nearby foes (small radius). In new runs from World 8: each 1% instead deals 25.6× your higher ranged or melee damage.

Effect by tier (roll range)

TierEffect
IKills explode for 1.4–2.6% of the slain enemy's max HP (small radius)
IIKills explode for 2.6–4.0% of the slain enemy's max HP (small radius)
IIIKills explode for 4–6% of the slain enemy's max HP (small radius)

Crafting always yields Tier I with a roll inside the range; merging three identical artifacts climbs a tier, reforging rerolls within the full range (a max roll shows as Perfect).
