Expert Tips

Vision of Empire (E) deals delayed damage and grants vision. Use it to check bushes and jungle entrances.
Demonic Ascension (R) drains HP every second. Activate it when 3+ enemies are within melee range, not at range.
Nevermove (W) root enables your R drain. Land W before activating R for reliable CC-into-drain combos.
