Slimum
by Lucas_Flin
Slimum, a Forge addon for Malum, adds two slime types, Soul Slime and Brilliant Slime, that players obtain through Splendid Slimes.
What it does
Slimum is a Splendid Slimes addon that brings slimes into the Malum magic mod. Its two new slimes come from plorts that turn into Soulstone or Brilliance, and players build their hearts by infusing a Slime Heart with ten different spirit types, with the eldritch spirit left out. The slimes also carry the effects of the mod's auras, where a happy aura gives nearby entities an Earthen effect or a glow, depending on the aura, while the mad aura Reject affects the area around it. Soul Slime hearts use Raw Soulstone, and Brilliant Slime hearts use clusters of brilliance.
Slimum requires Malum and Splendid Slimes, so both must be installed next to it. Installation covers the server and each player's game. Files are published for Forge 1.20.1 only, with version 1.0.1 as the latest file. The source code is public, and the mod is open source under the GNU General Public License v3.0 only.
