The Inevitability of Rust

The Inevitability of Rust is the third episode for the Inventor.

Title Double Rubble
Character Inventor
Episode Number 3
Description In a damp and grimy dungeon, some of your equipment is bound to break eventually. It's lucky you're so good at improvisation!
Rules Don't create gadgets after each fight. All equipment is reuseable. All equipment breaks after 4 uses. Broken equipment immediately becomes a gadget.
Unlock Requirements Unlock episodes by playing a game with five different characters

Basic Details

In this episode, the Inventor's pieces of equipment are only usable four times through the whole battle, with the uses left indicated by the dice on the top right. Equipment can be repaired through means like Grindstone, however.

On the other hand, equipment can be used multiple times in a turn, since it only breaks once it's out of uses. Once a piece of equipment breaks, it turns into the gadget it's meant to scrap to, and the gadget is re-enabled.

Similarly, the gadget also only has four uses before it becomes a Broken Gadget. However, it only has one use per turn, so ending your turn is required both to replenish your dice and to re-use the gadget.

Upgrading a piece of equipment will reset its uses back to 4 if the equipment upgraded has less than 4 uses remaining. Copying equipment will retain its number of uses.

If you use any equipment that has multiple uses, like Bump+ (2 uses per turn), its durability will only drop after being “fully” used (i.e. Bump+ used twice or Spanner+ used three times).

The Inventor starts with the gadget Focus, which does the same thing as her Limit Break, Focus.
