Leech Therapy
Leech Therapy
Throw a jar of leeches that attach to enemies, dealing spirit damage over time and eating away at the duration of enemy buffs.Read more
Wretched Vapors
Wretched Vapors
Crack open a vial to release an ethereal vapor onto yourself or an ally that causes a rush, then a crash.

Specter Rush: While it lasts, increases the speed of all actions and temporarily numbs all incoming damage creating looming specters.

Specter Crash: When the vapors wear off, all actions are slower and any remaining specters deal their delayed damage plus extra damage.

Incoming healing will prioritize removing specters first, preventing them from dealing damage.Read more
Healing Needles
Healing Needles
Load your weapon with a full clip of syringes that heal allies. Dealing damage recovers charges, and each leech you have collected slowly restores them.

Reloading spends a charge for a fresh clip.

Unused syringes are refunded as a partial charge. Recast to put them away.Read more
Lurking Terrors
Lurking Terrors
Open your bag and reveal the horrors you carry inside, dealing spirit damage over time to enemies in front of you. Enemies looking at you build up terror and cannot use stamina or movement abilities. At max terror, they flee in fear away from you.

Each leech you have collected adds fear duration.

Enemies facing away from you take 50% damage unless feared.

AP Order Explained

Because *ALL* of Harrow's Abilities are *Incredibly* powerful in Lane, you do not need to follow the provided AP Order at all. I implore you to look at who you are laning with, and against, and to allocate your AP based on what proves most effective for supporting your Allies. This is a very sound Build that allows you to not build Leeches first and still survive the Lane. PLEASE do not become a mindless bot. Play The Game. Do No Harm.
