[Archived] Undead Expansion

1.0.1

Small tweaks and balance changes:

- Grimstone is less common now,

- changed some recipes (vanilla crafting table),

- added polished Grimstone variant,

- Curse of Undeath now gives Slowness instead of Weakness II (somehow with weakness player couldnt deal damage in some cases),

- fixed Ghost spawning (it spawned everywhere, not only in Overworld and Soulsand Valley).
