Expert Tips

Absolution (passive) souls give damage, range, crit, and speed. Collect every soul — even in lost teamfights.
Curse of the Black Mist (E) conceals allies. Use it to conceal your ADC or a fed carry during a critical push.
Dawning Shadow (R) is global — look for low-HP targets across the map to confirm kills or saves simultaneously.
