This build is based on heavy supporting another person. In a way this person reaches invinciblity as long as none of the enchantments get removed. It is a perfect build to farm places with few creatures doing awfully high damage (like Underworld or augury rock).
So let's start with the Attributes:
Healing - As high as possible
Smiting - Unimportant for this build
Protection - min. 14
Divine Favor - As high as possible
And those are the skills you should bring along:
Protective Bond
Essence Bond
Life Bond
Balthazars Spirit
Signet of Devotion
Blessed Signet
Healing Seed
Skill at your disposal, could be Balthazars Aura if you got some points to spare on Smiting that is. Or you could bring Spellbreaker which might come in handy against enchantment removal.
Now what matters most about this build is the order of the spells:
1. Cast Protective Bond on your friend
2. Cast Essence Bond on your friend
3. Cast Life Bond on your friend
4. Cast Balthazars Spirit on yourself
5. Cast Blessed Signet until you are full on energy again
You're done. Now all you gotta do is cast healing seed on your friend and stay outta the aggro circle. Et voila, you have an invulnerable tank. How does this work? Well, protective bond limits the Hitpoints one can lose down to 5 %. Life Bond halves the damage taken again. Essence Bond gives you 1 energy whenever your ally is hit. As Life Bond transfers some of the damage to you... balthazars spirit gives you energy too. 1 per hit. But Life Bond also has some kind of damage reduction thus resulting in you getting zero damage but still counting hits. These 2 enchantments make up for the loss of 2 energy protective bond takes. Healing Seed is there to negate the little damage done. The signet of devotion is there to counter bleeding and health degen attacks. And finally, the blessed signet is used as your main source of energy income as the 4 enchantments drain all pips of energy regen.
I've tried this with a friend and we were able to farm UW with just this. I put up that enchantment spam on him and then went outta aggro range. Every 15-18 seconds i would go back, spam a signet of devotion on him, another healing seed and stepping back into safety again, using blessed signet to regain energy for another healing seed.
This said, there are actually 3 things you have to fear using this:
1 - stay away from aggro range. IMPORTANT! While your party member is invulnerable, you are not and you're a sitting duck this way too.
2 - stay away from enchantment removers unless you brought spellbreaker
3 - the lower the tanks hitpoints are, the better! Convince your friend to leave his vigor rune unequiped. If you can, convince him into using some superior runes.
Enjoy
