The game allows only 1 successful try - so it is:
floor 50 within 3m 52s at level 83.
doing the boss stage with pvp weapon.
the beginning is rough. pls see the whole run.
PS: every time I start recording smoothness goes away and there is no guarantee the skill would activate the moment I pressed it - there is some latency I dont trust. I play on a budget android smartphone with old 28nm GPU.
PPS: I let him hit me on purpose when my HP is full. I have to be on low HP otherwise my dps wont go thru boss`s HP regen.
