The previous Bosses weren't really difficult. Everyone only had to go through a few team wipes before they would be finished, but Heigan really wouldn't be that easy. Any one of the skills of this undead Mage could lead to a team wipe. The players had to pay the price of a few deaths to be able to learn the mechanisms of this Boss' skills.
However, Ruling Sword's players didn't. They already knew of Heigan's abilities ages ago.
"All the races of the world will eventually go extinct. This is just a matter of time."
"I can see limitless suffering, limitless torture… I can see the anger of heaven and earth – I see everything…"
"This world will be shaken very soon…"
"Your life is heading to its end."
"Starving worms will swallow up your rotten body."
This undead Mage left behind some classic lines as he died again at the hands of Lu Li and his team. This time, they only died once.
