While I'm not an RM, I am a berserker, and AFAIk we are affected by the augment cap unless we have marauder. (Wrath removes the cap). Therefore I think it was at least implied that an augment cap is in place for berserker rage. That may adversely change how your damage is calculated for the berserker druid.

Well shoot.
Okay, here is a revised version that obeys the augment cap, costs the same as Matt's list, and has 11 build to spare on whatever is wanted.
20 Damage list
Ogre Berserker Cleric
Ogre Wrath 10 (Str +1)
Monstrous Body 10 (Str +1)
Berserker (free)
Strength +3 45
Berserker Rage 5
Cleric (of Aguara or brazen)10
Lore Divinity 1
Clerics Weapon (2HE Blunt) 2
Sacrament Domain (0)
War Domain (0)
Prowess 1
1 FP free from opening the class
84 build, leaving 11 for what ever you want (as 95 is required for berserker rage)

Some fun, silly builds/scenarios:

Ogre Warrior Monk/Acrobat/Daredevil:
Soak=1 (ogre racial)+ 3 (iron body)+1 (defensive fighting)+4 (expert reflexes)+3 (expert agility)=12 while not wearing armor.

5 Vanguards in shield wall, each with hero's stance. For 30 seconds there is only one person in that shield wall capable of taking non-superior damage; the rest heal 50 body. Go team cheese grater!

You can only get 5 soak from non-armor non-rune sources (unless it's against a specific source), so most of that is moot.

Still, soak of 8 without having any hinderence ain't bad. Pick up warrior and it can go to 9 soak.

I've been thinking about this and everyone seems to be using mostly warrior and rogue classes. How about we switch this up?

Sylph Mage: Free class
Sphere of Influence: Fire (Free)
Lore: Magic (1)
Absorb Magic: (10)
Fire Strike: (1)
Rank 1 Fire Spell: (1)
Fireball: (2)
Magic Points: 30
(Staff, Small Weapon, Literacy and Adv. take the remaining 5 build)
50 build and I can consistently deal [strike]25[/strike] 30 (with the update) fire damage while still having enough build to read and fight with basic weapons. Absorb magic gets me 10 more uses (or 9 if I use Fire Strike to trigger it)
(Casting fire strike twice takes two mana and allows me to absorb magic. Please tell me if I'm not supposed to be eating my own fire.)

Challenge:

What is the least expensive way (build wise, no runes) to deal 20 damage with a melee weapon?

Show your work!

Technically, I am dealing 20 damage in this build and have a melee weapon in it. :lol:

Either way, a good attempt. Any build after that is going towards weaponcast, MP, or Incinerate.
