Heavyhand, Duel, Infantry Training, Body Development.
That's a great baseline.
If you have Wards (Toxic, Spirit, etc.) then re-spec them away. They are garbage-tier IMO.
Precision Strikes and Massive Criticals makes the most sense to get next.
One point of Magical Training can allow you to use a Scroll of Circle of Restoration, that's handy if a party member goes down, but IMO it's fine for a Warrior to chug Potions of Lesser Restoration and make Hirge do the Scrolls. But Magical Training does allow that to happen and some think it's worth a point for the flexibility.
Thanks,i only have the toxic ward because of the sewer of horrors and temple of sleepers that is almost impossible i still stuck in the mid of the quest.
I probably will go for massive criticals and precision strikes then.
OK, but if you have the right gear and potion you can get Resist Toxic up to 204 and whilst full immunity is 210 it shouldn't be an insurmountable health bleed, but of course then you can't have your favourite non-Toxic equipment. LOL at least you have a reason for it!
On a warrior?
If you feel a bit crazy and aren't afraid of spiders, you could always ramp up your Toxic resist super high until you become immune to poison... At that point, you can actually start a weird cult and become worshipped by venom-spitting spiders. Their worship will increase your HP to god levels! (Don't laugh, it works!)
