The captain was a Warrior and immediately used Charge. He most likely had a special effect on his equipment that increased the range of his Charge. Even though March Rain was very far away, he was still able to catch up to her.
At the same time, his teammates followed up on their captain.
Three Warriors, four Mages, two Warlocks, two Paladins, two Priests, a Shaman, two Druids, two Thieves and two Hunters – Lu Li had already familiarized himself with their team composition.
"Azure!" Lu Li yelled.
When Azure Sea Breeze used Shadowmeld, the Boss immediately aggroed onto March Rain and began running towards her. It found itself in between March Rain and the enemy Warriors that were Charging over.
The Boss was hit!
Charge wasn't a skill that took aggro; it was a crowd-control skill.
However, the Experience Reindeer was different to other Wild Bosses that were immune to crowd-control effects. The Reindeer became Stunned and the aggro was switched onto the enemy Warriors.
