Well, this build is not bad at all actually it is an amazing support with the best AoE in game. What matter here is the order of your classes, Wiz3>Thauma2>RC>Thauma3. From RC you will take “Rune of Destruction” as soon as possible since it is the best AoE dps in game (if you use it to kill single traget it sucks). Now, I strongly advice you to get Cafrisum asap and buying “Sacrament” and “Blessing” from pardoners since you will be autoattacking a lot, good thing is that your autoattack is extremly high (compared to other mages) since you will be adding attack with your buffs and also using Quick Cast attribute. Now it is boring until you reach Wiz3 (around lvl 42), after that is pretty easy until you reach Thauma2 (change is around 126, but it is not hard inmediatly, it becomes complicated after 140). And then it goes fun again once you reach RC (around lvl 177). Now, you will shine in party, playing this class alone is a bit meh. Now, most people will think you class is useless (ignorants) so it is a bit hard to find party but those who know the game will love to take you with them to world bosses and grind… if they don’t have a Chronomancer.
