Warlock Opinions?

[Kurotowa]

at higher levels a Warlock/rogue could deal out heavy damage. using retributive invisibility EB and liberal use of Sneack Attack lets the Warlock/Rogue deal out a healthy 15d6 damage per hit. With the greater blast shape evocation eldritch cone you have a chance of hitting several people at a time with it and with the dark shape eldritch doom you hit everyone within a 20' radius with this damage. Though I will admit that you must play the character a long while before you reap this benefit. but the heaping of skill points, ability to make your own scrolls, and the rogues sneaky abilities you can make one valuable party member.

Not really...

For starters, Sneak Attack only works when you make an attack roll. It doesn't work with Eldritch Cone or Eldritch Doom. Secondly, how do you get 15d6 damage? Eldritch Blast and Sneak Attack both advance at roughly 1d6 per two levels. Even if you pull out the Daggerspell Mage setup that's only getting you a combined 12d6 at 20th level. So your math is off or you're pulling in Epic level stats, which really aren't useful in a non-Epic conversation.

But welcome to ENworld, all the same.

If you want a legitimate way to 15d6 at 20th, then here you go. Either play a human or Xeph warlock and take the following feat chain:

1st - Point Blank Shot, (if Human, take Wild Talent as your bonus), 3rd - Psionic Shot, 6th - Maximize Spell-Like (blast), 9th - Improved Psionic Shot, 12th - Psionic Meditation, 15th - Quicken Spell-like (blast), 18th - Empower Spell-like (blast)

Equip your character with a Greater Chasuble of Fell Power (+2d6 to blast). Then take a move equivalent action every round to gain your psionic focus, then release your psionic focus when you shoot your eldritch blast.

9d6 (base) + 2d6 (chasuble) + 4d6 (imp psionic shot) = 15d6 every round.

Here's the beauty. Keep a Warlock's scepter around. If you start the round with your psionic focus (common in the first round of combat), fire a quickened-maximized-empowered imp psionic shot vitriolic blast with 2 scepter charges for an average of 132 points with your swift action. Then, with your move action collect your psionic focus. In your standard action fire a maximized-empowered imp psionic shot vitriolic blast with 3 scepter charges for an average of 140 points.

If you target has acid immunity you may have a problem, but that 272 points in one round that uses touch attack, ignores SR, and deals an additional 31 points per round for the next 4 rounds, for a grand total of 396 points, not counting any additional damage you are dealing to in the meantime.

That is not 'crud damage'.

EDIT: I understand that this is all a one-round one-trick pony, but the warlock's invocations give it flexibility, plus 15d6 every round ad infinitum is nothing to sneeze at.

Yup, being the only class that can take 10 on UMD is a huge advantage to the Warlock.

Artificers can too, for what it's worth.
