Hey I feel like such a noob asking this but here it goes. I have a lvl 10 warlock and i wanted to go into the prestige class, hellfire warlock, but i was a little confused about the details. I meet all the requirements to become one but i saw that in the fiendish codex II that it only has 3 levels. So my questions were when i enter the hellfire warlock class do i go straight to the level 1 hellfire warlock? and do I keep all of my abilities and invocations from my warlock levels? and after those 3 levels are up do i just go back to leveling up in the regular warlock class but with the abilities of a hellfire warlock? and while Im on this i might as well ask, when leveling up as a hellfire warlock it says you get +1 level of existing invoking class, what exactly does that mean? Thanks ahead for your help.
