Inferno adds a 5% chance to instantly complete another Smithing 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 can be shown as ${\frac {1}{100\%-Inferno*5\%}}-100\%$.

At a theoretical 20 buffs, inferno will chain proc infinitely until all materials are used or buff actions are depleted bringing inferno below 20.
