The point with this build is that insted of having the normal SS, MM, Bonder, Tank and Healer you take away the MM, the Healer and the tank and insted use a 600hp/Spiritbonding/whatever people call it monk. I've been able to clean SF several times with different people and i also had two Dragos Flatbow

1st Mo/Me (Spiritbonder)
Spirit Bond
Protective Spirit
Mantra of Resolve
Spellbreaker [E]
Blessed Signet
Divine Boon
Balthazars Spirit
Essence Bond
2nd Mo/X (Smitebonder)
Holy Wrath
Retribution
Life Attunement
Vital Blessing
Signet of Judgement [E]
Rage Signet
Purge Signet
Rebirth
N/Me (SS)
Spiteful Spirit [E]
Insidious Parasite
Arcane Echo
Spinal Shivers
Soul Feast
Drain Enchantment
Blood Ritual
Rescurrection Signet
Insted of N/Me you can also take a Me/Mo
Empathy
Backfire
Diversion
Drain Enchantment
Mantra of Recovery [E]
Ether Feast
Mind Burn
Rebirth
Okay, this is how you use all skills:
When you get out from Deldrimor Warcamp the Smitebonder put all enchants on the Spiritbonder (He shall have as much health he can and full 15armour)
The SS shall go for the Gnashers and Ice golems and use Soul Feast as selfheal and to remove corpses so gnashers cant make any wells / minions.
The Spiritbonder shall always use Protective Spirit-Spirit Bond right after eachother to block Protective spirit from getting shattered. So he will always have to have a look at his current enchantments.
The mesmer shall do damage with backfire and empathy but can also help by using diversion so the enemies can only attack normal and then they will take damage from holy wrath and retribution.
