I ran my first Lord of Blades today. I would like to make a suggetion.
If the columes are destroied it changes the energy that flows through them. When a person with mana stands near them it recharges the mana. There are cases in quest that have mana recharge points. In Reavers it is near the giant, in mindsunder it is when the bladders burst.
The quest is very mana intense for healers and I still don't think the option for end chest works the way it should.
