Passive, spells and ultimate

Pit Grit (P)

Sett's basic attacks alternate between left and right punch. Right punch is slightly stronger and faster. Sett also hates losing, gaining additional health regeneration based off of his missing health.

Playing against Sett

How to counter and exploit weaknesses

1

Dodge the center of his W (true damage): sidestep laterally, the cone is predictable.

2

Don't deal too much damage at once without killing him: he stores the damage for an even stronger W.

3

Kite him: Sett has no dash (except targeted R) and relies on Q speed to gap-close.

4

In teamfights, don't group behind your tank: his R slams the tank onto the carries.
