Ars Magica 2

Ars Magica 2 is a magical mod by Mithion. This mod is entirely different from the original, Ars Magica, which was not included in any FTB Modpack. Ars Magica 2 focuses on spellcasting, creation, bosses, and customization of spells. Unlike in Ars Magica, AM2 has the power to create highly custom spells, which you can tweak to your liking. Ars Magica 2 adds very powerful creatures to the world, Nether, and the Ender dimension. Additionally, you can summon highly dangerous bosses into the world, to gain special items. Ars Magica 2 has it's own experience system, which is used to level up, and gain more abilities for spell creation. The experience system is based on when you cast spells; each time you cast a spell successfully (eg: an offensive spell does damage to an entity), it will give you experience. The experience starts out to be a lot, but the more you use a spell, the less experience you will gain.
