|Mana Lens: Tripwire|
The Mana Lens: Tripwire is an item added by Botania. When put on a Mana Spreader it will only be able to fire any Mana bursts if there's at least one player or mob in the burst's path. It has no effect on Mana Prisms, and cannot be put on a Mana Blaster.
Composite Lenses made with the Tripwire lens as the secondary will not have this effect. This lens cannot be combined with the Mana Lens: Flare.
