Archon Mod

The Archon mod introduces magic into your Minecraft world. With this mod, you can have magical abilities in the game. This mod also adds new mobs and structures to the world, and some of those structures are captured by magicians and witches.

You can also find buildings/castles randomly spawned in the world, filled with spawners and other magic stuff. You can kill the mobs and use the spawners to gain some XP to upgrade your armor and enchantments. You can also find many new mobs spawning near the towers. You can kill these mobs to get their armor which is more potent than the casual ones.
