Solid Damage. I can't seem to consistently crack 400M on Hard. The Hydra Heads just spend too much time  under Serpent's Will. 

Something to think about:  IMO, You are wasting Thor's Top End potential having him sit in Trunda's Shadow on a Hard Hdyra Team.  There just isn''t enough Damage opportunity left to go around.  My Brutal Team does 550M+ and Thor does 300M himself.      

HYDRA HEAD FAKE?

For the last couple of months, Using Auto function Heroes attack the wrong Affinity Serpent Heads, when turning Auto off attempting to manually direct the attack the same thing occurs. Example : Magic Champion directed to attack a Spirit Serpent, goes the complete opposite direction & attacks a Force Serpent Head resulting in low damage. Is this Normal?  Because it happens more so than not, on Mobile & PC, Seems completely backwards to the rest of the games mechanics and AI logic. 🤷‍♂️

The only place that would make any sense would be if you are trying to attack the Mischief Head w/o Hex on it.

If you have a champ with counter attack that will happen.  My Gnut is all over the place on  counter attacks.  

@kramaswamy.kr .... You are playing the old school versiion.  I remember doing 2000 greenies manual for fusions.  

Speaking of Trunda, I pulled a 6* Awakening for her today.....but, I have no Trunda to put it on.

Worst I ever heard is someone doing 20k mysteries for the guranteed Michinaki.
