In nutshell the class has 2 modes: 1: Farm support 2: Low hp killer.
You should switch between the modes depending on the situation.
Farm support
Skill 2 3 4
Frostval Barbaria(FB) is a top tier farm support. It's able to bring the max crit damage out of a class. It's highly recommended to support classes with high crit damage like: Scarlet Sorceres(SS) or Vampire lord(VL).
Use this mode in cases where you have to fight 2 or more high hp monsters. (Like Forgotten Soul or Hydra Head 55 farming)
Low HP killer
Skill 5
If you face low HP monsters (below 5k hp), spam skill 5 to get instant kills in 3 sec average. (Example: Box guardian)
Skill 5 aplies Enrage: your haste is reduced by 100% but your damage is increased by 100%. Also removes Frostval Gifts (you cant spam buff so avoid skill 5 while supporting a party)
