I can tank almost anything in the game at any difficulty, but that dang white dragon in tor is owning me.
Between freezing me in place, so I can't move out of the way of his breath attack, and slowing me down so I can't melee effectively... he's just a beast.
I'm Epic 25 Pally Unyielding Sentinel.
Saves in the 50s.
AC120. PRR 148.
Elemental Resists in the 40s. (plus protection buffs on top)
Spell Absorption doesn't help.
I suppose I could switch my epic destiny up to have 30% elemental resist while blocking.
Would having a caster spam haste, dispel, I dunno what... help?
