Don't be a one trick pony. An optimized AC is an effective defense against most melee foes, but not against heavy arcane, or against those really big meat machines.
A lot of hit points, DR, and a good offense give you other options. And hopefully you aren't facing it by yourself.
Yep. A minor cloak of displacement is a very, very good investment also. Mine has paid off in spades. Still no DR for my thug other than
stoneskin, and I don't see that changing. But I also don't seem to really need it, so I'm good with that.
Touching on Caliban's comment about not facing it by yourself, I can't agree more. While I'm all about being self-sufficient (for example, most of my AC bonuses are from items rather than spells, and when they are from spells I've bought Pearls of Power to cover the spell slots required), teamwork can make up for a lot or just make two characters more than the sum of their parts. I play a fair amount with a high level druid and we work together really, really well. He provides me with a few buffs and support in combat, and I make sure that the bad guys don't get close to him unless he wants them to.
Some fun tricks:
The Half-Orc Delivery System: Half-orc with big sword delays. Caster summons an air elemental. Air elemental whirlwinds and goes around picking up the bad guys and the half-orc, who voluntarily fails his save to get picked up. Takes a little damage, but he's a Man(tm), so he doesn't complain. Air elemental goes somewhere and drops them all. Half-orc ends delay and commences the slaughter, great cleaving into all the enemies who are now around him.
The Wall of Half-Orc Pain: Prior to combat, Druid casts
freedom of movement on half-orc. During combat, druid drops a
wall of thorns on bad guys. Half-orc spring attacks into the wall of thorns, hits bad guy, spring attacks out. Rinse and repeat.
The Exploding Half-Orc: Druid casts
resist energy: fire on half-orc prior to combat. Druid casts
fire seeds: holly berry bombs and gives them to half-orc. Half-orc gets into a fight and is busy hacking away when the druid, safe in the back of the action, says the command word and the holly berries explode, doing massive damage to anyone within 5 feet of the half-orc. The half-orc is fine thanks to the energy resistance.
Anyways, just some ramblings on this Christmas morning.
