[spoiler]Man, that really makes me wish I got into that one game that's starting up. I was making a hellfire eldritch disciple that at the starting level (only into ED, no hellfire yet) had +15 to melee pre-Knowledge Devotion, two iterative melee touch attacks from BAB for eldritch glaive, and a ton of ways to get move actions as swift actions to offset the full-round casting.
At 20th it would have had 16 BAB (from fractional BAB- 15 without it), and thus 4 iterative touch attacks of 12d6 each, not counting bonus damage from KD and other sources, cast as a level 16 cleric (divine magician), level 11 warlock (3 least/lesser and 1 greater invocation), all sorts of awesome cleric and wizard spells, etc. etc. Pretty standard build, but with the houserules I think it would have been pretty kick ass (despite Divine Power being banned). I'm definitely gonna look into recreating it if I can manage in some future game.[/spoiler]
Spoilered to hide boring shit no one cares about.
