I have not seen any builds on here for a magicka focused Redguard that heals so I made one! Essentially this build will be identical to a typical healer/summoner sorcerer build.

When you are soloing or in a non-dungeon group, you will rely on skill slot 1. This slot will focus on summoning creatures to fight for you while you stand back and provide them with some healing via healing springs. Slot 2 is focused entirely on healing and should be used when you are in a group dungeon instance or public dungeon with others. Your main goal here is not to do damage, but heal and buff only.

The restoration staff here is your friend and you should only use this even when you are soloing. You can switch to a destruction staff skill line later if you plan accordingly. When attacking with the staff, I find it is better to do the heavy attack with the staff as not only does it provide you with magicka after a completed hit, but it also heals your nearby creatures/allies as well.
