Oh crap, I didn't check my messages before now (but I did a couple of battles this morning). I used the money to heal up, and went ahead and fought some kobolds... Well that was officially stupid of me. Now I'm half-healed and fully broke... :\
Well, it was my fault, and I don't mind entering the tournament like this...
BTW, when facing a bot, you can reload the page to change your attack options. Is that still valid when going against another player?
I think I'm good. I used the money (thanks, Morrus!) and have unequipped everything but the club. I wish I had some more money for some MP restoration, but I'm raring to go. Hopefully I'll get some posting in before the tourney starts.
Where can we find out which element is strong/weak against which other elements? I looked in the FAQ and didn't see it, but I might have missed something...
