Jefepato, all creatures played as player characters will use the THAC0 and Hit dice of the class they are, not based on race.<br/><br/>We are purely 2nd edition in terms of THAC0, and there are no limits to what race can play what (as in dwarven paladins are ok, anything that might limit race or level doesnt exsist.)<br/><br/><br/>Trolls lose their regenerative abilities to become PCs and you are right they are not in the complete book, no more then CHakats are, I am going to edit the numbers a bit to make these races work.<br/><br/>Since this is a "House rules" system game, i am not worried where we are I may ask a siren to move us later. For now we are fine here.<br/><br/>I hope I covered everything :)
