You should have fun in Tangleroot. There are very few if any DM surprises in there with suddenly filled rooms of mobs. (At least to a character with any sort of spot skill to notice the Hiding Bugbears). Thus it is pretty PD friendly in that respect. A few of the items on the end rewards are fairly nice as well. Most of my soloing, nonspell casting types will pick things/items that have nice clickies or summons spells on them. It is either STK or TR that has a staff that has MSIII on it (Scorpion) and that is useful. The Hell Hound summons are useful too, since they work well on thing like undead with their breath attacks, and be sure to get flanking with your pet and benefit from the extra sneak attack dice.
