In one of the games, I saw someone playing with close combat and shotgun shots (2nd skill). Every time after a shotgun shot, everything froze on the screen and it felt like 1 second passed.
This combination caused a lot of damage, so I decided to try it.
As it turned out, the game glitches...
If you use Mina's teleportation right before the stun (or slow) effect, Mina will not have another teleportation. She will also take full damage from the ability that caused the stun.
This can be reproduced by using teleportation literally in the last milliseconds before the stun.
