Pillar of Dark Energy

It is summoned by Vemiath, Chagorz, and Bakragore. It chains players who stands directly next to it, causing a chain spell that jumps up to 4 SQMs and deals damage according to the fight's characteristics. The chain spell sets 11 stacks to all characters hit by it. The stacks will cause damage per second to the players, each tick decreasing the number of stacks by one. In case a player with stacks gets hit by one of the bosses' beams, all the remaining stacks deal damage to the player at once and the number of stacks is reset.
