Playing against Seraphine
How to counter and exploit weaknesses
1
Spread out to avoid the R chaining — if an ally is hit, move away from them.
2
Her E alone only slows: it's dangerous ONLY if you're already slowed or CC'd.
3
Seraphine is immobile and squishy — assassins and flanks punish her well.
4
Her passive doubles every 3rd ability: if she has the visible halo, prepare for a double cast.
