Bonder Challenege

Hey everyone I've set myself a challenge to complete every dungeon possible using nothing but my ranger or assassin and 3 or less Bonder heroes.

I will add a progress report onto this thread and any info regarding ideas for builds or tactics would be greatly appreciated.

Thanks for your help guys

Progress

Cathedral of flames - done
Snowman lair - done

I can see it revolve around
1. 3x Bonders with 13 Prot and Prot Bond. That will reduce energy loss to 1/monk.
2. Troll Unguent, because it's unstrippable. Although it's slow and can be interrupted.
3. Cover enchantments to protect your precious bonds.
4. Yourself bringing maximum offense.
