A regenner's job is to regen.
To do this, you need 'regen' or 'complete heal'.
You also need to know BEFOREHAND who you are primarily regenning. This consists of the
buddy system.
You regen your primary target and also keep track of who is being
ganged up on the most. If you type group, you can see a very spammy list of how much hp most everyone has. If
you can quickly decipher this, you can give someone who needs hp hp.
You're likely to get hit in combat a lot. You should set up a way
with your buddy to know when you should be rescued. You dont necessarily need to regen and rescue constantly,
but at least often enough to stay alive. This may well be constantly in some stressful situations.
You also need to be poisoned to avoid being strangled.
