I'm looking at updating my 32-point, level 25 Warforged pure Wizard for update 19. I want to stay pure for the purposes of flexibility, so I won't be adding any splashes that I might be stuck with later, as I have no plans for TR'ing. I'll get the expansion pack eventually.
My current feats are:
Toughness
Insightful Reflexes
Heighten
Quicken
Empower
Maximize
Mental Toughness
SF: Conjuration
SF: Evocation
GSF: Evocation
Spell Pen
Greater Spell Pen
Epic Spell Pen
Great Intelligence
Because I like to dabble in DC casting, I am hesitant to dump the feats that make it possible to switch to Magister and be effective. I'm not too concerned about the Spell Focus feats, you only need one to unlock the Magister DC lines, they are no longer necessary for AM and most DC increases come through Int, ED's and enhancements. I can barely make the Spell Pen checks as it is with the full compliment of bonuses, I don't want to find myself in a situation where stuff is only landing on mobs with less than Drow SR only half the time, otherwise I'd consider dumping that line for more Mental Toughness.
If I can find room for a single SF feat, I think that will be enough to unlock most of the possible DC bonuses. I'm thinking Conjuration for that, spammable Web is still the best CC for those who aren't hitting the DC ceiling, which I won't be. So I'm thinking drop SF/GSF Evocation for Improved Mental Toughness and Enlarge, keep the Spell Pen line to keep spells like Otto's Irresistible Dance relevant and take Epic Mental Toughness when I get the expansion. I won't know whether Great Intelligence is worth keeping until I figure out what gear is possible, but I could possibly take a 2nd Spell Focus or perhaps Epic Toughness if I start with 18 Con. I haven't looked into the post-U19 stuff in any real depth, so any thoughts?
