Yet Another Stats Upgrader Mod, Isn't?

Definitely not balanced whatsoever, USE AT YOUR OWN DISCRETION.

Untested in Multiplayer, please do report if you find any bugs.

Check Bestiary to see upgrader's drop rates.

~~There's +40 Damage and/or +5 Defense limit per-item in Pre-Harmode. ~~
~~+80 Damage and/or +10 Defense limit per-item in Pre-Moon Lord. ~~
~~For Summon-type weapon, damage will increase on ALL currently summoned minion/sentry ONLY when you hold summon-type weapon with upgraded stats. ~~
~~Normal and Summon attack upgrader are inter-craftable by hands. ~~
Removed these limitations because why imposing hardcoded limit if you have SELF RESTRAIN.

Note: - Might incompatible with any reforging method, use Resetter item first before you reforge.

• Item that changes upon being right-clicked (Example: Thor's Hammer from Thorium mod) cannot be upgraded and will glitch itself if doing so. You have been warned.
