I had the pleasure of trying the Crystalline Entity for the first time today. (The event's usual timeslots don't seem to be very Europe-compatible, so it took some time.)
What astonished me most is that there are many people in the zone chat who are pretty sure they know what to do and what not to do, to the point of being very insulting to everyone who does not do exactly what they mean is right - even when there is clear evidence that they are wrong. And many of those people contradict each other, which is all the more funny.
There seems to be an STO legend that projectile weapons should not be used against the Crystalline Entity and/or its fragments. Some say it will directly heal the entitiy, some say it will cause more fragments to appear, some say it has no effect at all. The Wiki page does not say anything about not using projectile weapons, and the ops text does not say anything about that, either. However, using torpedoes, I could not observe anything but that the entitiy's health goes down from any type of weapon.
But of course, I could be mistaken by my own perception, so: What are the real facts reagarding the CE?
i was there, the torpedo one was about using torp spread on large fragments, they make small fragments that go back to the CE and heal it. thats not bad info, thats correct.
you use any combat pets or anything that can cause the big fragments to split and cause small fragments, they go back and heal and you are no closer to your goal.
as for flying in circles, that is only meant for those who have multiple shards after them, usually adjusting all power to engines gives you the chance to outrun the shards. but only when you are far enough away from the CE can you dispose of the big shards and small shards, you would need to be very precise about it with your team and damn fast when dealing with the small shards while trying not to cause even more big shards nearby to break. it is recommended you just not shoot them and have the shards follow.
the thing that ended it was 3 players in the group clearly not responding when they use photonic fleet and mines, even boarding shuttles. stuff like this makes the job harder when it gets to 30% HP. its a simple thing, avoid the big shards and keep them from exploding while taking down the CE. after about 20 minutes i gave up and wished everyone luck then did some STFs.
Hitting the shards with torpedos is fine, hitting them with a destructible object ( including your own ship) is not.
Destructible objects include plasma/tricobalt high yields, that fancy new klingon missile, boarding shuttles, any kind if mine including cluster torpedo.
If a large fragment is hitting any destructible object it has succeeded to deliver it's payload somewhere and causes 3 small fragments to return to the main entity healing it 1% each on top of it's natural regen.
Imagine 3 large frags doing this, imagine 15 doing this and you can see why the entity can jump back to almost full in a second.
Some people say AoE damage affects the large frags the same way. I don't know if this is true but AoE damage makes short work of small frags as well, so gravity wells for example should be fine if they have some distance of the main entity.
give us your full list of 'urban legends' so no one is confused about what you consider to be unreliable on the CE. hopefully enough people contribute to this thread where a basic agreement is shared about what should and should not be done, that would be as close as you get to clearing up this urban legends problem.
