The summon food was just an example, actually I don't know if I'll use food in the gameKnockOut wrote: You can have weapons and spells always do the same amount of damage per level but only accuracy is affected by random chance. Of course members of the party who miss would not get their spells to go up as much. But then you'd want to get hit by your opponents so you could cast heal more so your healers gain more heal xp.
I can't think of good ways to prevent abuse other than of course the ways we already mentioned breakable items, time limits. Maybe breakable spells?
What you mean "weapon/spells do the same amount of damage per level"? you mean proportional damage?
What I think to do is increase the spell stats proportionally to the level and sum the usage.
Example fire bolt basic, 1-3dmg and 15% hit chance
At level 10, 10-30dmg and 25% hit chance and so on.
It would affect damage, duration, hit chance, etc for each spell.
Of course you could want to let your fighters be hit more to be healed more, but being hit more=more damage to the armours. I could counterbalance this checking the actual difficulty of the fight, or other ways. Anyway I hope not everyone playing the game will think about cheating!
