Ursus the Mighty is a massive beast and the first ever raid boss in Maplestory.

Story

Masarayu was a man who had everything, his fortunes matched those of Gold Richie, and he had nothing to fear. Then one day, he heard about Ursus, a beast who displayed the very power and anger of nature itself. Ursus cared not for wealth nor riches, and his sheer power made Masarayu dub him "The Mighty". A bounty was put on Ursus's head, and now heroes and adventurers line up to fight him in droves.

Battle Overview

Ursus is the first ever raid boss in Maplestory, and this means that his fight isn't anything like what you've experienced before. After completing the prequests from the notifier on the left side of the screen, you can head to Ursus at any time through the Dimensional Mirror in towns, or via the Boss Tab.

You can only use 8 skills while fighting Ursus, and you select them before entering the fight. Once you enter, you cannot change the skills that you picked, so coordinate party buffs with your party members to maximize the amount of powerful attacks that everyone can select. This is what the UI looks like.

Note that the passive effects from all of your skills are applied, regardless of whether or not you select them as 1 of the 8 skills to take into the fight.

You can fight Ursus with 1-18 people, separated into up to 3 parties of 6 players each.

Your group gets 80 shared lives; once they run out, the run is over. You can use up to 20 potions per life.
Ursus has an individual ranking system for each player. In increasing order, you can earn E, D, C, B, A, S, SS, and SSS ranks upon the end of the fight. Your rank is based on a number of factors including damage dealt, revives, time taken, deaths etc.... Higher ranks come with higher rewards.
Ursus has no time limit, but if you take too long to kill him you will automatically be assigned the lowest rank.
Ursus drops no items, instead you are awarded items based on your rank during the fight.
Ursus has an entry limit of 3 entries per account per day.

Rewards

Players are awarded a variety of body parts from Ursus depending on their rank during the fight. They can redeem these with Aisha for a variety of items, including Clean Slate Scroll 10%, Spell Traces, damage skins, chairs, and temporary Cash Shop gear. You can also obtain a number of medals and titles through fighting Ursus. You may also talk to Jawad to claim any medals, Soul Shards, or a special title.
