The only way to counter all this powerful PVE strategies is Puffoxin 
I try the power of cryo today, I reach 71 floors (1224-1295) with only 2 cryowyrm, 3 subzeratobs and 2 dreadwolf. I used 5 healers to keep cryowyrms alive. With the water ocarina (+30%) cryo is much more stronger than frillzeon and much more resistant (about 2.9k life for cryo!). This monster is so OP !
They don’t?
As I posted on the previous page, Cryo has a higher magic stat (albeit by only about 15%) than Frillzeon. It has better defense and resist, as well as HP, but a much, much lower speed.
Also, unless you are Crystal, I doubt you’ll have 30 Cryo haha… I only have a level 50 Cryo.
I have 3 level 99 Cryowyrms 
With 3 cryo, the +30% ocarina, and few healers, the infinit dongeon isn’t a problem anymore !
I have two Cryos at the moment. The only OM I don’t have two of is Octoneer. The only ones I have more of are scorpionix and triphoon.
I feel like Cyrowyrm is off topic…
Plasmorex ftw
When this topic was made nobody could really comment on Cryowyrm as it wasn’t released. I’ll rename it.
