From Dota 2 Wiki
Vhoul Assassin is a neutral creep found in:

- The debuff from multiple Vhoul Assassins' successive attacks does not stack, only the duration gets refreshed.
- The attacks first apply their damage, then the debuff.
- Deals damage in 1 second intervals, starting 1 second after the debuff is placed, resutling in 10 (20 against non-hero units) instances.
- Can deal up to 20 (40 to non-hero units) damage (before reductions).
- Envenomed Weapon's damage is not lethal.
