Viscous Ball is not triggering the cooldown for tankbuster, resulting in tankbuster dealing more damage than the ball hitting you constantly. Match ID 35772930, you can review the death logs or damage logs when he is balling after he unlocks tankbuster and it makes his ultimate very deadly.
Stamina Mastery is only giving Vyper 1 stamina instead of 2 stamina when 2 upgrades have been selected in slither that provides 2 stamina. Instead of having 8 stamina you only have 7.
Just a visual bug where you can only view up to 7 stamina
Vypers tier 3 slither resistances do not function. I am not receiving 25% spirit or bullet resist while sliding. All of the damage I receive shows amplified by 12-16% when I do not have other sources of resist.
Sliding up the side stairway near the guardian on the side lanes backwards results...
