I was thinking, given the Bladeforged's helpful switch from -Cha to -Dex, that perhaps a Bladeforged Sorcerer-Paladin might work (at least, ridiculously good saves plus a Reconstruct SLA seems nice). Given I would be multiclassing a melee anyway (barring LR+1 shenanigans), perhaps this might be a home for Eldritch Knight.

Sadly it's a choice between toggle-Tensers and Eldritch Tempest versus wings. Fond as I am of wings, I probably come down on the side of the EK tier 5s. There's still room to go up to core 5 in Air and get knockdown immunity if I feel that way inclined. (I think immunity to petrification is pretty minor and immunity to paralysis is pointless for bladeforged, but I do like knockdown immunity).

Is an 18/2 split the way to go? It gives me level 9 spells on the Sorc side, and Lay on Hands/Divine Grace on the Paladin side, but there's always the option of taking Paladin up to 6 and pursuing Sacred Defender, or bringing a third class into the mix.

With all the ASF reduction in Bladeforged and EK, I think I could even grab Adamantine Body with 0% ASF - is that worth it after the AC changes? I wasn't around for those, but I have a vague idea that Adamantine Body now scales with level?
