My water support I'm making is going to be mostly a reviver so I won't be focusing as much on INT as a normal water support but I will be adding enough INT to at least get water thunder skill.

Level 34 atm with 53 WIS 3 INT and 51 CON

Because I'm use bow to train I will be getting CON to 65 and then shift over to INT which will give me water thunder by level 60 or so.

AGI isn't something you need unless you intend to do a lot of pk battles. otherwise just focus on equipment that adds to speed.
