Hmm, that would be interesting if "Reflect" was made into a chance stat like connserve MP. Like some new pieces of gear would come with "Reflect +x" which would increase the chance of reflect activating by x%. They could easily give out the spell then since it isn't 100%.

Though thinking about it, reflect may not exactly be the best choice since the spells that monsters cast tend to be spells they would be resistant too, or even healed by them.
