How to Use Decay

Who should buy Decay?

Players who want a direct anti-heal application without needing repeated weapon buildup.

When to activate or apply it

Apply it before committing into the target's sustain. Keep the fight focused during the damage-over-time and healing-reduction window.

Against Lady Geist: Apply Decay before the finish attempt. Strong healing reduction plus current-health damage attacks the exact sustain window she relies on to survive while low.

Watch out for

Owning anti-heal is not enough if the application comes after the healing trade has already turned the fight. It also does not replace distance or control.

Check your team’s anti-heal applications. Repeating the same source does not add another independent healing-reduction effect; distinct sources can combine with diminishing returns. Choose a source you can apply reliably before adding another purchase.

When to Buy Decay in Deadlock

Buy it when healing is extending fights and your build cannot reliably apply another anti-heal option. Make the purchase before the next sustain-heavy engagement and use it as your team commits.

Best Against

High-health sustain targets and fights where healing is preventing a finish.

Baba →

Her health and sustain build keeps surviving our damage

Choose Toxic Bullets if you can maintain weapon hits, or Decay for targeted healing reduction. Apply it before the sustain window.

Both combine percentage-health damage with anti-heal. They are situational against healing items or upgraded Granny Long Legs melee lifesteal; anti-heal does not counter the barrier from Soothing Brew.

Lady Geist →

She keeps stabilizing at low health

Apply Decay before the finish attempt.

Strong healing reduction plus current-health damage attacks the exact sustain window she relies on to survive while low.

Victor →

He keeps healing through every attempt to finish him

Apply Decay or another reliably applied anti-heal source before committing, and track his cleanse.

Healing reduction is valuable only while it remains applied; coordinated reapplication or denying the next sustain cast can be necessary to finish Victor.
