There are generally three stages of the Crystalline Entity of which you should be aware.
High Health
Between about 66% and 100% Hit Points, the Entity will send out Crystalline Fragments. These regular-sized enemies will follow players that aggro it. Within 1 km of starships or any target-able weapons, they will explode. The damage they inflict goes through all forms of shields and directly damages your hull. It is at this stage that the Entity fires its antiproton beam weapon at whichever player currently has aggro on it; this beam weapon inflicts shield damage as normal beam weapons would do.
Medium Health
Between about 33% and 66%, the Entity will stop firing its beam weapon and will send off Crystalline Fragments at a faster rate than before.
Low Health
Below 33%, the Entity begins to send off Large Crystalline Fragments (as well as the regular Fragments from before), which are faster and do nearly twice the damage of regular Fragments. If they explode from hitting a starship — or a mine or heavy torpedo — they will then spawn three Small Crystalline Fragments, which then head back toward the Entity, carrying the energy from their splintering back to it to heal it for roughly 1% of its health each — 3% total.
It is important for some players to focus on the Small Crystalline Fragments and destroy them so that they do not return to the Entity to heal it, while most of the other players continue to focus their attacks on the Entity itself.
It is generally recommended to focus on:
1.Outrunning the Large Crystalline Fragments at all times (so as to not be destroyed by them, and to not allow them to splinter into Small Fragments to heal the Entity) while kiting them;
2.Firing at the Entity to lower its health;
3.Using special abilities to temporarily debuff, confuse, or halt the Entity, its attacks, and its creation of Fragments; and
4.Staying at least 5 km away from the Entity during the third stage when Large Fragments will splinter into Small Fragments if impacted.
Equipment for your ships:
Use everywhere Beam Arrays or Cannons , no Torpedos or mines !
Use single Fire buffs like Rapid Fire, Beam Overload , dont use area buffs like Beam Fire at Will or Scatter Valley (and of course no torpedo skills!)
