Hello I bean playing aion with a full miragents templar. Was the third dude on Siel server with full mriagents.
So why would you need evasion with a templar furgive this don't manastone slot within evasion manastone.
How shild block work, will depend on your opponent if your oppoenent have 1500 accuracy you can have 2000 shield block for a rate of 10% ea 100 shield block over. So you can have a maximum of 50% shield block, so 500 points in shield block over your opponent.
and for Physical attack it's infinit.
So if your a guy that love using shield, go look on aion online the best assasin in your server, and look is accuracy so you'll know witch average of points you need to have in shield block and if your a greatsword user try to get arround 300 crit and all the other manastone slot full them up with attack stone.
