There are Many fine Specs Ive tested for the 2 slot Naj.. the one that pulls ahead damage wise is the armor ignore , Frez whirl ninja build.. as it allows for the single target burst of armor ignore while also allowing for the aoe burst of frez whirl... plus math wise frez whirl is a very strong single target move as well... hitting for a combined total of 150-250 after all 120ed out..and it gets to keep its poisoning skill. just make sure to take this route for your first round of training as the slot jump bug will not be fixed until pub 98.. In round one fix resist( 80 80 (leave frost as is ) 100 rest into energy) ,give it armor ignore and frez whirl,Increase mana reg to 30, and stam reg to 5-9, this should leave you with enough points to increase mana abit... don't go over 400 mana in this first round as math wise you will be super close to a slot jump.. Hope this helps abit mate . =^-^=
