Mod suggestion: increase item by stats using it

[NKSHV]

like the "learn by doing mod"
just damage enemies with weapon and it will have additional damage, speed, size, etc.
use drill and it will become bigger and faster
take damage with armor and get additional defence
etc.
additional stats should be subtle like in learn by doing

There's a mod called the Do it with a Copper Shortsword mod. It makes a copper shortsword deal 1 more damage for every 10 enemies it kills
