First check

Which route can Plague Wards observe, and where can allies fight around the slow?

On your team

Play as Venomancer

Set Plague Wards on a route your team plans to use so the vision and pressure serve the next move.
Use Venomous Gale when allies can continue the trade, then leave before enemies reach your backline position.
Keep the wave moving after a favorable fight so damage over time becomes control of a real objective.

On the enemy team

Play against Venomancer

Clear wards along the route before a slow push reveals every movement into Venomancer’s area.
Disengage from repeated poison trades and return with a fresh wave rather than lingering at low health.
Approach from more than one angle so a single Gale cannot delay the whole team’s entry.

One replay drill

Make the lesson stick

For three ward setups, record vision gained, enemy route, allied follow-up, and objective effect.
