Juniper Hart

Semblance
Devotion: Juniper has the power to mark up to two enemies with a small Sigil for 5 seconds, which glows under their feet. The Sigil does nothing on its own, but upon her making any successful melee or ranged attack, it stores 50% of the initial strike's damage to redistribute to its target as a small concussive explosion.

The main drawbacks to this Semblance are that a marked enemy can run away, which makes marking that specific enemy useless. In between every two marks, Juniper must wait an additional 15 seconds before producing more; and she cannot detonate them early, she must wait the full 5 seconds and then the additional 15. This cooldown also does not apply if she has one mark left, but another will not become available until she expends both marks.
