This achievement is unlocked for completing all ten rounds of Mayhem at the Arena Grand without the aid of a group in 15 minutes or less. The timer for this is pretty tight, especially with the current difficulty curve in 7.0. Some key important things to remember about the fights are;

• Keeping your companion, preferably a level 50 dual wielding melee or Shae Viszla/Altur/B3-S1, in DPS spec will help you burn down the bosses quicker. The only fight where you will want to swap your dps companion out for a melee healer is for the Breaktown brawler fight. You will want to make sure that you set your companion's target (default CTRL+1) during the fight or else they may end up attacking the wrong boss or mob. Remember that having a higher Presence stat will improve the effectiveness of your companion as well.

• Intermissions between each round count towards the total 15 minutes, and these, combined with the final explosion for Zotar, adds up to 04:23, or just under a third of the total time of the achievement. Add in the extra time for running to the console and progressing through the conversation and you have about 10 minutes for combat, or roughly 1 minute for each boss fight.

• Using the legacy Unity ability and a maximum unlocked Heroic Moment will help for fights with higher damage, as will adrenals and medpacs. Although none of these are explicitly required to get the achievement, they will make surviving, and thus not wasting time on respawns, easier.

• Any DPS spec can beat the timer for the achievement, however you should choose a class that you are comfortable with and understand quite well. You will need to utilize defensives and crowd controls (stuns, interrupts, knockbacks) to help beat the timers for the fights.

• The first 5 bosses are all relatively easy and straightforward, and if you can average at or under 20 seconds for each fight you will be on track for unlocking the achievement. This gives you about 15-20 extra seconds for the last 5 bosses which are slightly longer because of adds, mechanics, or just boss health. If you can average 80-85 seconds on the last 5 bosses you will make it with time to spare for the achievement.

• Some general tips for each round are below, but you will likely need to practice to get the timer.

  • Round 1: (DPS comp) destroy the Medical Unit AZ-01 then burn Arlaia Zayzan

  • Round 2: (DPS comp) burn Daruula Grah

  • Round 3: (DPS comp) burn Gungus Boga

  • Round 4: (DPS comp) burn Chompers and once he starts channeling Regenerating... burn Conrad Om'wurt

  • Round 5: (DPS comp) burn Lanos, and when the Reprogrammed Skytrooper Shielders spawn stun or knock them back, then continue burning Lanos

  • Round 6: (heal melee comp) burn one skinflayer, then the other, and finally burn down Breaktown Brawler Thades Gorkultok, DOTs are extremely helpful here as they are not reflected

  • Round 7: (heal comp) burn Drake Raven then burn Nocturno

  • Round 8: (DPS comp) burn Little Gut

  • Round 9: (DPS comp) burn the Doom droid, make sure to keep the laser pointed away from your companion, and watch out for the exploding Assault Unit AZ-A that spawn

  • Round 10: (heal comp) burn After Shock and every time Eternal Champion Zotar comes down swap to him

Mayhem at the Arena Grand

100 Legacy Points   |   Grants Legacy Title: Deathless Champion on completion

This achievement is unlocked for completing all ten rounds of Mayhem at the Arena Grand without the aid of a group and without dying. The survivability of these fights has gotten slightly easier with later expansions. Having medpacs on standby, as well as any class abilities that buff health, heroic moment, and the companion ability Unity will all help to unlock this achievement. Taking your time on this can be helpful, and it may be best to get this at a separate time from Sprint Champion. The mission needed to complete this is;
