Is it just me, or is the in-game description of this ability a little vague? Does this ability deal damage to all frigates around the LRF for a short while (if you hover over the button, a small purple ring appears around the unit, I don't really have an idea what else it would indicate), or does the regular attack gain splash damage when using Cluster Warheads? I messed around a bit with this ability, but I couldn't figure it out. Also, how long does it last?
No site I've found seems to really answer these questions, so could someone here give me a little breakdown?
