Heaven's Lament | The Veil

Heaven's Toll (Sentry)
When you click, ring the bell three times. A bell's sentient head will answer your call. It trails behind you wherever you go, staring down the nearest enemy within 100 studs and firing twin eye beams every 1.5 seconds that burst for 12 damage. You may have one sentry standing at a time. Costs 150 stamina
