Enemies standing on structures affected by B.A.S.E. are snared by 15%. Enemies that damage a structure affected by B.A.S.E. are frozen for 4 seconds. Each enemy can be frozen once every 15 seconds
A very good B.A.S.E. build for Frostnite which allows for you to practically stall if you're low on mats. Traps are buffed too in order to provide maximum stall.
