Well, I built him to 40th. I'd post the build so both of us can read it later
, but might as well shorthand it here. Barbarian Fighter Weapon Master - no tumble or UMD. But, scythe with AB 66 with Bless/Aid/Rages, and 13 fighter levels to get a 28% chance of the Fighter Widget to trigger.
Regarding Taunt:
Toon has Intimidate and Taunt of 50 with no buffs or items.
Greater Rage OR Mighty Rage increase Taunt by 10; together they stack.
Full Mighty/Greater Rage Taunt is 70 (plus 1d20) for a taunt of between 71 and 90.
Half-Spider Scrappers DC is 32
Corrupted Orc Thrall DC is 54
Shagrat DC is 80
Osgiliath Revenant Boss DC 65(Giants are DC between 10 and 18).
If you have a Mordor tank that can get me close enough, I'd love to try and taunt some of the Gondor bosses and see how they stack up.
