Silencer

Use Arcane Curse when you expect opponents to cast a spell.

Clicking Glaives of Wisdom on an enemy hero doesn't draw creep aggro.

To steal intelligence from a dying hero you have to have Glaives of Wisdom skilled and be within 925 of dying hero or be the one who scores the kill.

Combining Arcane Curse with Last Word does a lot of damage.

Be aware of what happens on the map, so you can use Global Silence when needed.

Using Global Silence defensively is fine, but ideally use it during fights. Make moves when it is off cooldown.

Many items dispel Global Silence. Be patient and don't waste it at the start of a fight.

Glaives of Wisdom are great for harassing as Silencer doesn't pull aggro and the damage ramps up.

Silencer's Arcane Curse gets extended every time you cast a spell while under the effect of it.

Global Silence has a long cooldown. Look to fight after it was used.

Items that provide dispel are great against Silencer's silences.
