It is currently possible to accumulate an absurd amount of mitigation on the Tank, I will use my character as an example

This is my character, just with normal buffs and without any bugs and has 54.9% physical mitigation
Now I will only use the skills "Fortify", "Rush Of Courage" and "Aegis" once, one after the other, in this order.

And this is my new physical mitigation 63,9%
If I repeat this process a few times

And this is my new physical mitigation 93.9%
This bug can be accumulated even more and only goes away when the player relogs or dies.
This bug is extremely strong and needs to be fixed immediately.
