Dead Cells – Forge
Forge (also known as Foundry) can be found after each of the bosses and only then. In there you can permanently upgrade chances for your weapons to drop with +, ++, and S quality. Each of those quality levels will add to the weapon or skill extra damage, stronger and additional affixes (the effects like +100% damage on burning enemies). Aside from that ++ upgrade guarantees you +1 to the tier (Brutality, Tactics, or Survival) to which this item belongs and S upgrade will give you +2. In the case of items that belong to two tiers, the tier bonus will be randomly generated within those two tiers – for example for [Cursed Sword S], you can get +2 tactics or + 2 brutality or +1 tactics and +1 brutality.
You can upgrade gear by spending cells which goes as follow:
- 1000 cells for 100% chance for + quality gear
- 3500 cells for 60% chance of ++ quality gear
- 8000 cells for a 30% chance of S quality gear
Those are permanent progress bars so you’ll be able to have benefited from those every time you spend enough cells to reach each 5% milestone (as in 5%, 10%, 15%, and so on). You can’t exceed the 60% cap for ++ nor 30% for S quality gear.
