Inferno adds a 5% chance to instantly complete another Smithing or Cooking action. The extra action consumes the normal amount of ingredients and buff stacks and can activate further infernos.

Uses

Since inferno can proc on itself, the speed gained is exponential and the average time taken to smith or cook is $time=baseTime*(1-Inferno*5\%)$.

Inferno is capped at 80% but cannot be reached even with a full 7 buff shrine. (75% max)

At a theoretical 20 buffs (if ignoring the cap), inferno will chain proc infinitely until all materials are used or buff actions are depleted bringing inferno below 20.
