What should I make, and how should I do the stats? Just made a guardian, almost level 2. Is that a good choice?

Not a bad choice. To my knowledge and experience Guardian is a healing catacombs character, not really a solo climber !

Your stats should be +5vita / +5intelligence / Rest into intelligence

Or

+10 vita / rest into intelligence

It could be alot of different things but so I'd recommend tweaking it with your different guild to find the most effective build but either of those will be ok to start.

Ahh I see, what about a solo character? My guild is slowly dieing so, making a class as a healer would be pretty useless most likely.

if you want to solo I would probably make a mag, pump all into int upgrade charms every 10 levels

alright thanks. I'll give that a go.
