The title describes the issue: in the end, there are a large number of UNKILLABLE end crystals, this number is so large that the end dragon will always eventually gain more health than I can drain, and I am using a maxed out power 4 draconic bow, and am still unable to over time prevent the dragon from gaining all of the health it lost, as recently for some reason the dragon being unspawnable bug fixed itsself, I attempted to spawn & kill a dragon, and I cannot do it because there are just too many end crystals, and they can't be killed
