Dex/spr mages? What am I even reading. Dex is totally useless in PvE, a simple aim scroll will cover 99% of your aim needs even if you have the crappiest gears. Would only consider DEX for seasoned PvPers that want to have a chance at hitting some of the most evasive classes in game
If you make regular use of SC, you dont need any SPR as you can easily hit the cap with costumes/accessories and in game items. Once you are freed of such worries any point you put in STR or INT is scalable extra dmg in both PvE and PvP and therefore the superior choice to maximize your effectiveness
If you play on a budget SPR is however a must
What are the sources or reproducible tests about DDF reaper gears adding 10% crit to party?
