As long as i get to be the frog
In general to have fast low round combat that means a PC can take alot of damage in a hurry. Usually they go from perfectly fine to in the danger zone in a single round - meaning they don’t typically have time to take a defensive action before they are already in trouble.It also helps if you have more skill, allies, or planning than your opponents. But that goes beyond this thread's considerations...
Avoiding damage? What about Dodge, Disengage, Dash, and Ready actions? Other party members can take some damage too - that's why they wore armor.
I don't know. I always thought "you don't die today" was a good outcome of healing.
Is there honestly a shortage of these options?
