Skills for lith harbor arena characters

If tell a person to go to Lith Harbor and play against someone, the battle will most likely take a few minutes and it may be not a very interesting battle if all the arena characters just attack, use nimble feet or use an Orange potion, that's why I am suggesting that each character have skills to make the battle more interesting, but don't make the skills too powerful or too repetitive, and I also found that when I went to the battle arena, if an enemy used an Orange Potion, it would not work and really just make the enemy skip their turn, I also suggest that you fix this error.

orange potion does works it just doesnt shows the recovered hp the enemy has.
but you can see it in the bar.
and only a few chars got skills like slashblast like mr.basil lol.

I know, but all i'm suggesting is give more characters some more skills if possible, but I guess it won't be done because I know how hard Rpg maker xp is to use and creating custom skills and more frames will have to be made and it's more work but try to get a least a few more people skills,
