I have a lvl 11 gadgeteer that is already very close to having both dex/senses maxed. Now my question is what attributes are worth maxing after dex/senses. I was thinking Pie/Vit...vit for more life and pie for more stamina. Vit gives me iron body and pie gives me iron will...both are nice to have IMHO.

I don't really think any points into speed will be useful as I have a designated haste caster. Also I don't think I need to put any more points into intelligence (60 without items) as I already learn skills pretty fast...also gadgies don't have much place to place skill points so I can just improve the skills by leveling up. Also power cast is useless for Gadgie.

I don't plan to go melee so strength isn't all that useful...again power strike is useless for gadgie.

Comments or advice needed...

seems like you have decided what you want. strength is usefull so that your character can hold more items or wear more heavy armor. intellect is useful for those that use magic.

not much thing put to put those points then except for Vit.

Fung, you'll need strength. You'll soon get so many good gadgets, that weigh a lot. At the end of my game, my gadgeteer had around 75 str, and still had a yellow Encumberance.

Str is important in the later part of the game. It also helps build some stamina, as those higher gadgets soak up more and more stamina. I would also work on Vitality for both HP and stamina.
