Nano Crystal - Creates a powerful, yet specialised force field around all the people in the engineer's team. This field will remain dormant until the person is attacked by a special attack, such as Burst or Full Auto. When such an attack upon the person is made, the field comes instantly to life and fully absorbs the effects of that attack. This shield can absorb 7 special attacks before being rendered useless. The field around the members in the team will be refreshed every minute.
