Just use alot of mines and overcharged weapons.. Mines will Hurt if bad fast especially if you get the plasma variety that do a dot to it. While I havent fought it since open beta if you mine the area real good before it spawns it will get chewed up fast and you can stack your damage on it with phasers and torps while the mines pummel it.
Sides the Crystaline entity destroyed planets eco systems entirely ripping the life from them so it could grow on its own. Its not supposed to be easy to kill tho i say give Wesley crusher a tuning fork a tricorder and some bubble gum and hed prolly figure out how to shatter the thing all over again on his own.
I just did the Fleet Action.
Its hilarious with these weaker ships again.
There were so many Mirandas, i told them to all join this instance.
Best part was when the Entity was spawn camping.
It kept setting off Miranda chain reactions. LOL
But in the end we beat it.
Im the one with most damage btw. :p
He's killable. It just took a while. We had 6 ships, all tier 1, and finally had to designate people to shoot shoot down the shards and stay at long range. It took about 10 minutes once we got a strategy down, and probably 30 minutes total from the time we first engaged him.
