From Guild Wars 2 Wiki
“Deploys a turret that heals you briefly, then regenerates you and your allies.
— In-game description [?]
- The initial heal happens upon the turret's creation.
- The turret triggers every 3 seconds. Staying in the turret's area will maintain regeneration as long as the turret exists.
- This turret's overcharge ability Cleansing Burst applies when the turret next fires, not instantly.
- Activating Detonate Healing Turret while Cleansing Burst is active will still trigger the AoE Healing combo.
