The Aboleth bites and stabs at Ancalagon when he approaches in ooze form, and those attacks manage to do precisely nothing. The biggest form of damage seems to come from some spell it has on itself, and although he can grip it fiercely, slowly dissolving the calamari upstart, the crackle of deathly energies, the element of death, peace and stillness, erodes at his very core all the while.<br/><br/>(23 negative energy damage taken, and it's not dead yet. It does seem to have been weakened, however, judging by the strength of it thrashing about. Keep squeezing?)
