The sample build is set up to have high surviveability along with decent static damage. You have 2 encounter "resist 5 for a turn" powers to use to chase static modifiers, along with some equipment daily powers to do the same.
When you do get hit 3-4 times in a single round and are still standing, use the Bracers for two attacks, and follow it with Fury's Advance for a third. Then spend an action point, and talk your Warlord into giving you at least one more. 4 Attacks at +24-36 will really hurt something.
The background, a lot of late paragon feats and early epic feats are going to Sage of the Age's utility power, so that you can usually get 3-4 or the benefits. The ritual caster things are just tossed in there because it looks like it would work well with Sage of Ages and a silly high Arcana check.
