Right click to remove from a socket., in case of being overrun by Plummeting Ursas. It That Fell's melee damage is comparable to one of those Ursas, but it has higher attack speed, especially when enraged. The safest way to deal with this boss is to clear summoned Ursas as soon as possible, wait out the enrage and use the limited time before it uses the Neo maneuver again to deal damage. The pack of Ursas is usually 4-6 strong and there's a danger of being surprised later on by those that didn't drop initially. A good way to avoid that is to walk around the edges of the Earthquake the boss leaves behind when jumping. There seems to be no limit to how many Ursas can be summoned.
