It has been some time since I have played a caster in epics. I have 27 more racial PLs (9 Races) and 10 more EPLs to go so my plan is to take my build from 1-30 once every 3 racial lives. I have 6mm Karma in all spheres at this point so really just looking for efficiency/ease/speed of going from 20-30. I'm assuming I will go either Draconic or Magister but figured I would ask in case there was another option that is attractive. Also looking for "must have" twists, I have been twisting sense weakness and grim precision for so long I have no clue what makes sense for casters. Thanks
