Healer's Handbook

Behind every great team of adventurers, there is a skilled healer. Without a skilled healer, even the mightiest of adventurers wouldn't stand a chance against the most powerful opponent of all - God. You are this healer. Unfortunately, your adventurers are not the most powerful. In fact, they're really not very powerful at all. They have no business challenging God. And yet, here we are. Sigh. They just insist they can do it. They have no chance. You know it. God knows it. But I guess we'll go through the motions.

You've sworn the Hippocratic Oath. Your hands are tied. You must keep these adventurers alive as long as possible - no matter how inevitable their fate may be.

Inscribe runes on your spellbook to cast healing spells. Maybe if you keep them alive long enough, the adventurers will at least like try to attack or something at some point.
