Good Morning Ragnar, Once upon a time adding to much to a given stat would cause a slot jump..but they fixed that issue in pub 98.. so you can add as much as you like without fear of this happening. A very important thing to know is that as of pub 97 int no longer increases mana pool... So don't invest in int.. you will have to go under stats and mana to increase that now.. You will find with the 2 slot naj often you will struggle to spend all the points as its already so close to stat cap on so many things... but there are many fine builds for them.. One of my favorites is the Armor ignore, frenz whirl build.. This gives it strong single target and aoe( area of effect) damage... and as its ninja skill grows so does the str of the frez whirl.. You want to take this skill to 120 if you pick this build. I would avoid armor pierce as it falls rather short when compared to armor ignore... as for its main attack.. you want to make sure to cap its str out at 700 this will be one of your largest damage increase, after that each lvl,3,4,5 you want to go under stats and damage per sec and max that out.. as this will be your 2nd largest increase.. Don't over look the stats dex and stam, Increases these 150 increases( gives the pet an extra melee swing every 1.5 sec and ground speed by roughly 20%). As these pets don't have any healing moves you want to give it 20 HP reg, and 30 mana regen for sustained dps... with the aoe build of frez whirl and/or poison breath you want to give it at least 5-9 stam regen so it stays at full swing speed when being pounded at spawns or other spawn heavy areas.. The best advice I can honestly give you is make a few copies of your tamer to test over the time of a few days, in new heaven you will find 2 gates, one bonds pets, the other takes them to 100% training ,and lets you test builds and order or doing things.. I would head there and toy with a few builds and see which ones you like... If you like I will even meet you there and help ya with orders and such... hope this helped mate.. if ya have anymore questions feel free to post or message me.. =^-^=
