• Resourceful Indeed - If the player also has [Partially-Eaten Cheese] , [Rat Boots] , and [Resourceful Sack] , the player becomes the Resourceful Rat, preventing items from being stolen when they're left behind in rooms. [Lich's Eye Bullets] does not activate this synergy on its own, but can still trigger its synergy message if the player has this gun and two other Rat items. The [Lich's Eye Bullets] can only act as one of the remaining items in the synergy,
• Elimentaler will not reveal secret room walls, nor can be fed to Munchers .
• Enemies can be encheesed while in invulnerable states (such as Shelletons while turning into a skull), forcing the player to wait until the effect wears off.
• The pool of cheese left behind by enemies will put out the fireplace in the Keep of the Lead Lord .
• Elimentaler is one of the few guns in the game with perfect accuracy, with its accuracy unaffected even by accuracy reducing items such as [Eyepatch] .
• Enemies such as Pinheads and Nitras will not explode if killed while encheesed.
• Additional shots fired due to the effects of the Y.V. shrine will be of the same projectile type as the first shot of the burst.

Pick it up after finding it in one of the Resourceful Rat's chests .
