Renaissance core is a thaumcraft addon, also core of my modpack ThaumicRenaissanceKedition.
this mod added:
Bubble wrap golem, a golem immune "stuck in wall" damage.
You now can behead pech's head by using ReForbidden Magic's Skull axe item, those skull can use to craft golem.
Arcane cleansing dust, a dust can clear crucible instantly without any pollution, but no output also.
