Way too based on luck
I find that nearly 90% of the time skills are useless and waste your MP as they were placed wrong. Even using the Healing set, half the time it doesn't work and you just drain your MP, and then when you need it again, you still have no MP. Other times your health just drops incredibly fast, and you cant use the Healing skills to attempt to make up for lost ground. I understand that your are probably aware of using dice has a flaw, but this is such a major issue as you have no control over your roll, let alone if your skills work or not. If you give the player better control over the skills (such as use it on all of your dice, not just on position) then it would potentially be much more fun to play
