@Vektor Cryo 3 chrono 3 is one of the best support wizard builds out there next to thaumaturge linker.
Full con is generally what you will be gunning for since this is a very support oriented makeup. Only thing with full con is that after about level 140’ish you pretty much need to be in a party at all times to level since you do NO damage whatsoever beyond snowball even with arde dagger, cafrisun, and priest buffs.
So if you have the ability to level with friends/guild on the regular, this is what you want to do. You can put into int if you want to solo and don’t have people to level with, and can just use a stat reset if you have one. If you don’t have a reset it isn’t a huge deal, though you will be a bit squishy later on.
As far as skills you can do what you like, since there is always the ability to use a skill reset whenever. Though, I generally just make sure to have 5/5 on snowball and tree along with saving points through Chrono in order to max out Quicken and Haste as soon as you get them.
Source: I use the same build / knowledge of the game from those who have played since cbt.
@nacho_ph Cryo and chrono have fairly cheap attributes, though the most beneficial in my opinion would be:
Chrono: Quicken crit rate attribute, Haste evasion attribute, Slow crit resistance attribute
Cryo: Shield mastery enchant, Freeze speciality, Ice bolt chance of freeze
Wizard: Maximum buff count, Lethargy additional dmg (used to boost cleric’s dmg ALOT)
Granted these attributes have support in mind and not damage.
You’ll want plate armor mastery as well if you are supporting.
