Starter dungeon build help
Well, save yourself is probably the shout he’s looking for. Then maybe healing breeze for his heal? mace + focus/shield. Other than that I don’t think a guard has a lot of aoe healing. Much of his healing has a small aoe (mace symbol, symbol healing). You might wanna get Knight’s gear.
I think this makes a fairly decent base for what your friend is looking for.

Since there’re various ways to build for “never going down”, I’ve left that open.
Save Yourselves and the Honor trait Pure of Voice apply to eating conditions, along with any other shouts.
Hold the Line, Mace auto attack, Mace and Staff Symbols, Shield of Absorption, and Tome of Courage all apply to throwing out heals.
Have your friend consider these, and plop in/rework for whatever else catches his fancy.
