I'm planning a Warforged Archmage, with 12 feats to choose.
Planning to have 2x Focus on Necromancy (for high save DC), 1x Focus on Conjuration (for web SLA) and 1x Focus on Enchantment (for hypnotism SLA).
That's 4 feats, then there's Mental Toughness (required), Maximize, Empower, Heighten, Quicken, 2x Spell Penetration, Toughness, Insightful Reflexes.
That's 13 feats, but I can only have 12. Which one would you drop?
With the Past Life feat, which one would you drop after that?
I'm considering Toughness, Insightful Reflexes and the Spell Penetration line. Between Toughness and Insightful Reflexes, I feel the latter would help more toward survivability in epics, since Toughness is just 42 hp while a halved spell easily accounts for a hundred damage. Spell Penetration I'd rather not drop but after a couple past lives it might be a valid choice.
What's your advice?
