July 2010: The eratta to free action attacks and especially bloodiron led to a huge drop of damage, but 211 DPR is still quite good, since many other high DPR builds were also hit. The build works better with radiant cheese (morninglord + boon etc), but a) Morninglord is a very likely candidate for the next update and b) i wanted to keep the essence of a crithunter intact, even if the benfits are not as huge as before...
The Executioner
(Avenger/Ardent Champion/Eternal Defender)
Build Goal:There are many Avenger builds, but most focus on getting 18-20 crit range or abusing Punisher of the Gods and Swordmaster. This build is to show that a more conventional heavy axe wielding Avenger can also be very competitive, without sacrificing defenses or getting laughs for his little knife

Bit of conditional damage:
If we scored a critical hit, the enemy is prone due to reaving axe slayer. If he tries to stand up, we get a OA MBA (a). If he stays down, our whole attack next round will benefit from combat advantage and headmans chop (b).
a) 0.655*(53)+0.2125*(156) = 67.87 multiplied by 0.3798 crit chance = 25.78
b) 0.665*(45) + 0.2125*(148) + 0.665*(45) + 0.2125*(148) + 0.3798*0.665*(53) + 0.3798*0.2125*(156) + 0.96*(14)= 162.17 = 16.28 difference, multiplied by 0.3798 crit chance = 6.18 dpr
I shall assume he chooses b) to minimize damage, but he actually might choose a to have a better chance to hit.

Tactics & Conclusion
Great At-Will Damage:Its safe to say that the Executioner won't lack good at-will damage with an average DPR of
211 DPR ...

This damage includes damage from one of our dancing kopeshs+4, which we can and will use 5 encounters per day. Pure at-will damage without dancing weapon:
156 DPR. But our two avenger powers are not useless, covering ranged attacks (Radiant Vengeance) and tactical repositioning (Overwhelming Strike).
OK Defenses: Since our secondary is Strength, there is no good way to use armor of faith+cloth, so we have to use chain. However, an AC of 46 and NADs of 40/40/41 is not that bad. If necessary, a war ring can be switched for shadow band.
Interesting Powers:The very high At-will damage puts us in an interesting situation: We cannot choose any daily or encounter attack power which deals more damage than twin strike. This leaves the powers with interesting effects - and the Avenger certainly has a well sorted supply of those. Here are the highlights:
The
Temple of Resolution (daily) creates a encounter lasting 5x5 zone of radiant damage (25 for entering, 25 for ending the turn). Its supposed to keep everyone out - but guess where everyone in your party will put his enemies

for free damage.
Scatter to the Astral Winds (encounter). Teleport every enemy (but your target) 5 squares. Great for tactical movement, or at the edge of a volcano (or the wizards wall of fire). At worst, you can teleport everyone adjacent to you, for 23 damage from your rain of steel.
Phase Duel: removing someone from battle can be great, removing yourself from battle can be great. Phase Duel does both, and you can even attack the removed enemy !
Utility: High perception, ok insight. Good speed, ignoring difficult terrain due to flying, and ok initiative (+22) makes sure our prey cannot escape. We fly up 20 squares with a double running move (and 1/encounter up to 40 squares), which allows us to reach most interesting places. Walk through walls for 1 full encounter (phasing) can also be very useful outside combat, like scouting the whole dungeon by walking inside the walls, moving through the big steel vault door etc. Ritual Caster is also very useful, especially with so many trained class skills...
