Eximus Rework & Mastery Rank 27 Test

[PrincessCestra]

I think the Mastery Rank 27 test could use some balancing after the recent Eximus rework.  You're already fighting the clock, the platforming, losing points if you die, taking more damage as you get points, and having to kill Eximus to get more points... they're increased tankiness just makes it seem unfair.  Even if you can dish & take damage, it just plain takes longer to kill them now and that really eats away at the clock.
