Light Mages are new mobs added by Ars Magica 2. They spawn rarely. They are dressed in bright clothing, commonly in white robes, as opposed to the black ones worn by the Dark Mages. They hold what appears to be a blue Affinity Tome. However, if they are disarmed, no tome is dropped. They will attack hostile mobs with a projectile "spell," dealing around 8 damage. If killed, they can drop Spell Parchment, Spell Books, and Runes.
Working with Light Mages
If you have the Mage Posse Talent, and an open Summon slot, you can right click on them and they will join your "team", following you around and attempting to protect you. If you have the Mage Posse II talent, they will Mana Link with you, giving you access to their mana pool to cast spells. There will be a blue, medium-thickness beam connecting it to you. If, for some reason, you would like to dismiss them from your team, just right click on them again.
