The warlock class is a great combat and solo class thier buffs r self only but they last 24 hrs on paper and they don't have a limit to how many times they can use there powers. They have a very limited amount of powers (much much more limited then sorcerer) but again they have infinte uses. They really are a 1 trick class and the 1 trick is there eldritch blast but they can get other powers 2 modify wat effect that attack does. They base eldritch blast is on a d6 on certian lvl system (kinda like rogue's sneak attack d6) the eldritch blast is a single target attack but 1 of the powers is called chian now wat it does is the 1st target takes the full E blast (E for eldritch) then it bounces to 1 foe per 4 lvls every foe after the 1st takes half the total d6 (say he/she has a 4d6 blast base dmg so if he/she hit the 1st target it takes the full 4d6 the blast then jumps 2 the nearest target and on a sucessful hit of the 2nd target that target takes only 2d6 and if there is a 3rd target hit it would only take 1d6)
