ok, im a lvl 23 pure int nuker and i have 19 heuksal, 20 lighning, 20 ice, 19 bicheon and 15 fire. so i was thinking of this build: 90 Lighning/ 90 Ice/ 90 Bicheon and 30 hueksal. but i found out that u can still be immune to status effects even if u have 30 fire.
and i have seen a lot of pure int raising fire to 30 instead of heuksal. i chose to lvl heuksal cause i would love some hp and i would lvl faster to 30 with it. but should lvl fire to 30 instead? i will get some physical damage, magical defense and the immune to status effects thing. plus i will have the fire nuke to use after my lightning nuke

. but i am not sure, cause i like to live longer then kill faster. pls tell which one i should choose 30 heuksal or 30 fire

.
and should i use the ice nuke in pve cause in the guides it says they are useless and do very low damage.
