Mortis the Flaming Sear

Overview
Mortis the Flaming Sear is the boss of the 9th Floor of the game, Va' Rok. It has a spawn time of 2 minutes and 40 seconds depending on server lag.

Strategy
You can farm this boss by luring it to the teleporter behind the chair in the boss room since it cannot walk over them. Go on top one of the crystals at the teleporter. Another way is barely squeezing in two people on the top of the crystal. Additionally, you can farm the boss by climbing up the purple torch, jumping on top of an Undead Berserker, and roll-jumping/use rapier special onto a pillar.

Mortis the Flaming Sear has a lot of health, so killing it with a team would be more convenient.

Trivia
Question
 * This is the first boss to have 5 HP bars.
 * "Mortis" means death in Latin.
 * This is the first boss to have 1,000,000 or more HP.
 * Mortis the Flaming Sear is similar to a character in Dota 2 named "Shadow Fiend."
 * The Horns is now only dropped by the Gargoyle Reaper in Version 87 servers of the game, which makes its drops guaranteed to be legendary.

So The Floor 9 Boss Drops 6 legendaires so each legendary is 0.1%  then does that mean all the legendaires added up make the drop chance 0.6%
