So in the title update, AL has been slightly reduced (THANK YOU 343!).
When you barrage someone with plasma as they cling to the ground in armor lock, their energy drains away.
SO…
What happens if someone uses AL and gets rammed by a high-velocity, boosting ghost?
a) Both perish in a spectacular explosion. (big bang theory)
b) They simply phase through each-other; unharmed and unaware.
c) Ghost evaporates.
d) AL user evaporates.
e) The two cannot co-exist in the same universe, and so such an occurrence will not arise.
f) Space-time bends. Dimensional distortion. And Chuck Norris dies.
