Cleon
Legend
Epic massive towers made of stone! If we can't cajole Cleon into going higher by reminding him that the DR replaces hardness, let's at least do DR 15/adamantine.
I stand firm on DR 15/adamantine.

Regarding the feats, flards have psi-like abilities, so they can't take Mental Resistance or Force of Will. And I don't know whether Quicken SLA works on Ps abilities. In any case, we can replace two of those three with more epic feats!
Good point on the Mental Resistance and Force of Wil.
Quicken SLA does work on psionic abilities so I reckon we should keep it.
Their aren't that many Epic Feats it's eligible for apart from Epic Toughness, Epic Prowess, the ability-improving Epic Feats and Epic Fortitude (the latter of which isn't much use to it).
Maybe Epic Toughness, plus Ability Focus (Cone of Cold) instead of the other Epic Feat?
