Hello all. I have found something interesting as I was doing research for a hack and slash game I am in. Going to Faiths of Eberron on page 84 there is a PrC called Thief of Life (I can be wrong as the book is not in front of me so pardon on the name). It is a very interesting class as it offers something usually reserved for undead characters that costs them a feat. The entry requirements are roughly, four ranks in Heal and Knowledge Arcana, two ranks in Knowledge Religion (I may have switch the knowledges in terms of ranks but I know it is just these two for sure), sneak attack 2d6, humanoid or monsterous humanois, as well as a worshiper of Vol. So nothing to crazy for requirements. The class goes for ten levels but I suggest only going four. At levels 2, 6, 10 one gains a d6 to sneak attack up to 3d6. The class also gains things if a equal level or higher CR baddie is killed by sneak attack. Things like temp hit points, immunity to fatigue and such, and even no aging penalties for a year. The class also has things like immunity to negative energy, fear, and something else. The kicker is this, every odd level starting from 1 a character gains lifesense of five feet. So by ninth level you have it at 25 feet. Not to shabby and felt that scouting classes may find this info useful.
