IF you can stand keeping a 4 gap until 60+ and then farm (maybe farm at 16 too?)
Then i would definitely advise a
Pacheon 70 / cold 70 / fire 70 / lightning 70 build (or maybe throw in heuksal passive lv 2-3 instead)
In 5 years haha, when you reach lv 90, do curst heart a little bit and make it look like this:
Pacheon 90 / cold 60 / fire 60 / lightning 60
Uhm regarding ice, the passive + buff is like +100 psy defense when maxed, which is a LOT.
Frost nova is also extremly useful and fun aswell. When being gangbanged while training throw nova woods to freeze/frostbite everyone around you. Its also sweet for pvp, if youre maybe fighting a glavier who starts off the fight with getting a lucky stun. Smack all three nova books at him to regain hp - phantom walk away and restart the fight to your advantage
Also frostbite is so fking brilliant for pvp for an archer. (you should get both fire and cold imbue though)
Sorry if it got a little long, had a lot of caffein today
