One funny thing to note is that Chimaeron is a bit harder to kill if you play an undead
To solo Chima you need to stay the closest above 10k health and use shields. Let's say you're at 10400hp. Fury Ward absorbs 90k dmg, if you're taking for instance a 1 Million hit, you'll only take 400 dmg and only those 400dmg will be absorbed, leaving 89.6k absorb on your shield.
So it's really trivial (and boring) to solo this boss as long as you have enough dps in Dark Apotheosis. Just keep your Fury Ward up the whole fight and you won't take any dmg.
But as an undead you'll get random heals from Touch of the Grave, so you'll need to react and use Burning Rush to lower your health.
Not hard, just tricky.
