What it does

The mod is a Splendid Slimes addon that adds two new slime types inspired by Iron's Spells 'n Spellbooks. Ink Slimes produce arcane ink from their plorts, and the rarity of that ink rises with its power. Runic Slimes produce blank runestones, which are a little more common than the ink. Both slimes can be found in the wild, and their hearts can also be obtained in three different ways.

Wild ink and runic slimes are reactive to Iron's Spells mages. Mages will start attacking them with Magic Missile or Eldritch Blast when they come near, and some slimes levitate because of the energy inside them. Slimes that are hungry will teleport straight to food. Heart items can be found in chests around Iron's Spells dungeons. Fusing a slime with another slime carrying huge magic power makes it unstable, and it cannot be turned back. The Slime Press converts 64 plorts into the matching output, and it also turns a blank runestone into the Ink Slime Heart or Runic Slime Heart.
