Good Derv build for Abbadons Mouth?

Can anyone help me with a build that works with a Derv for Abbadons Mouth Mission? Im guessing tanking would be a good start, but dont really have anything to protect me.

I was thinking of keeping these skills for the mission
Vital Boon (+60HP, 117HP When ends)
Avatar of Balthazar ?

Would they do any good? I know the +40 armor would come in handy.

Anyone can suggest a good build/skills? Balthazar wouldn't be useful here there are no undead monsters to take advantage of holy damage and +40 armor isn't going to help that much.

Avatar of Melandru would be a much better choice for the immunity to burning.

When I did this mission and when I was cappin skills for the skill hunter title in this mission I just ran an Avatar of Lyssa build with mystic regeneration to counter the burning.

[skill]great dwarf armor[/skill]
[skill]mystic regeneration[/skill]
[skill]avatar of lyssa[/skill]
[skill]aura of holy might[/skill]
[skill]eternal aura[/skill]
[skill]heart of fury[/skill]
[skill]mystic sweep[/skill]
[skill]eremite's attack[/skill]

On another note the build posted by pyro is a pvp build... notice it doesn't have eternal aura to keep Avatar of Melandru up which is a little bit of a boo boo. If you wanna run Melandru run something like this;

[skill]avatar of melandru[/skill]
[skill]wearying strike[/skill]
[skill]eternal aura[/skill]
[skill]heart of fury[/skill]

Rest of the skills are up to you.
