A few notes:
Most damage you take in battle can be easily healed just by general posting in the folder. A good example of that is, just from
his general posts, the damage that Meganaraku took this round from the mercyclops is basically already healed up in a sense.
(IE, he gained more xp from posting and general stuff than he lost from the attack, so it's technically a net gain).
There is also however "healing" which hasn't come up yet but will at some point.
Depending on the abilities a character receives through their weapons, tomes etc, some will be able to heal in combat.
The way that works is, if for example somebody had that ability, and used it on their turn to heal the damage Meganaraku took,he'd actually not lose the xp from that hit. Or lose less.
And speaking of that, as people get their Noble "Keep" threads, you should be checking in with your OP, as you'll find your abilities listed there. You'll get more as you go up level.
The abilities you get will be based on who you are squiring for and what path you have chosen (in the Sealab folder it's "Liquor" or "Vengeance").
But everybody (not just noobull) has and will get various new abilities as things progress.
