The Blind Well is an activity that mixes what Destiny 1 people called Archeon's Forge and Court of Oryx.
To activate the Blind Well you require a Charge of Light. They can drop from all different activities within Dreaming City and also they are available to buy from Petra too. There are 3 Tiers; Tier I, Tier II and Tier III ( there is talk about that it has a fourth tier due to whats available to buy from Petra).
Once you deposit a Charge into the main centre core of the Blind Well, you will activate the Tier I,II or III. You then hold different control points with the sole of objective of killing the enemy to charge each point to 100%. Once you have done 4 waves, with each control point in a different place, you then have the boss or bosses.
To kill bosses, you need to kill a High Value Target that glows silver. He drops a Harmony orb which allows you to damage the bosses super. Once the shield is down then anyone can do damage as much as they like.
Tier I - 1 Boss
Tier II - 2 Bosses
Tier III - 3 Bosses (combbination of Tier I and Tier II bosses)
Currently Tier II completions reward a rare chance for a Sedd of Light. This allows you to activate anothe one of your supers. There is also talk that Tier 3 will drop you your 3rd subclass Super but I haven't seen this yet.
Very hectic but quite good fun,.
