Sauron and Beast synergy not working

leogo2

I was testing my 6* Beast with the Sauron synergy.



Basically Beast gains 2 permanent fury buffs when hp is below 50% and 20%. One at a time of course.

This however doesn't seem to work right.

When Beast gets below those percentages he gains the fury normally.



But when he starts a fight with his hp already below 50% or 20% the fury doesn't come in.



Can somebody test this if it happens aswell?
Thanks for the help.
