Nullstone is a relic item in UnderMine. It costs 3 
Major Curses at Sho'guul's lair.
This item blocks one attack per room and reappears when the player enters a new room. It negates almost all types of damage (including from Sacrifice Rooms and 
Purge Potions), except Mortar's beam attack and fire damage from landing on a torch. Blocking hits prevents status effects from afflicting the player (e.g., a Spider's poisonous bite or projectiles from 
Waking Light-affected Torches and wall lanterns). Blocking a hit prevents the 
Intensifier's effect from resetting.
The Nullstone activates after 
Wayland's Boots, 
Floating Skull, and 
Mirror Shield.
When the Nullstone disappears, any 
Will o' the Wisps on the player will be removed.
Tips[]
Because the nullstone blocks damage taken from buying items with health from 
Blood Offering, it can easily be used to clear out shops with no cost. You can buy an item, enter a new room, go back and buy another item, and repeat this process.
