I see. I shall change that.

okay, did a lil researching on the rank exp rewards
Using Munir as the base of this test

Round 4 (Nightfall Vicar/Vanguard/Arcanist), reward "120" rank exp
At the end of the fight, but prior to the last hit (Munir skipped the turn, other two pets KO'd last enemy):

Bolt (Rank 2) 2% | Ice Barrier (r1) 63.38% | Tidal Surge (r1) 56.93% | Ice Sphere (r1) 18.73%

Post-fight (it seems rank exp reward is awarded automatically along with the regular exp when you win, and that 'claim reward' is presumably for the material rewards):

Bolt (Rank 2) 5.01% | Ice Barrier (r1) 69.38% | Tidal Surge (r1) 62.93% | Ice Sphere (r1) 24.73%

So the r2 Bolt gained +3%, and the three r1 attacks gained +6%

-~-~-
Adding:
Round 5 (wait, that was Elaine?)
Rank exp reward: 160

before battle end:
Bolt(r2) 5.30% | IB(r1) 69.50% | TS(r1) 62.95% | IS(r1) 25.53%

after:
Bolt(r2) 9.30% | IB(r1) 77.50% | TS(r1) 70.96% | IS(r1) 33.53%

so r2 = +4%, r1= +8%

Double posting because I remembered to check the genescans of MoM Elaine and her Vicars

(+70,000 HP, +50Str+Int, +100Dex+Agi)

also, MoM Elaine's look, which doesn't actually use an avatar image and is instead its own thing





"Where's Demora's though?" You ask, and the answer is "I killed her and then realised we hadn't checked her stats"

Images of MoM nightfall people, just in case anyone needs them:



Just as with Eleane, they are actually their own images and not proper avatars.

Back around to stage 8 again, still extremely hard. Not sure if it's 100% accurate, but it seems like if a pet has a colored debuff and is the pet to kill a plasma of the same color, then it receives the same colored buff. It's happened several times. It appears if something such as X pet's bleeding kills it, then it counts as that pet killing it.

If it is how to trigger the buffs for sure. Aim to get the blue and yellow buff on your attacker.

Thanks again so much for the guide, I was finally able to beat the behemoth! It took a lot of tries and it mostly felt like luck, I'm almost positive I'm missing an important fight mechanic.

The only thing I noticed about my better tries was I believe I didn't attack the plasmas through 5-3 stacks of the mitigation buff they get and I blocked with all pets when the plasmas got to 3 stacks of the mitigation buff.

These are the pets I used to fight him. The earth tank had rank 3 on the first attack and rank 2 on the rest when I beat the behemoth, the light and air pets had rank 4 on everything. :)

congratz!

Thanks! :)

I keep trying but can't seem to beat the summons fast enough to prevent Behemoth from healing up all the way.

Also, there have been times I know for sure my earth pet has a taunt up on Behemoth, and Behemoth crashes through my air and light pets instead. What am I doing wrong??

Maybe Artemesia would be better help but I can try. I've beat the behemoth three times now.

First of all what pets and gear are you using?
