| Actually, its possible to stand outside the gate and summon your pet inside. Command it to go as far in as you can see, that should provoke Cerberus to attack and if you can target him, then open the gate and attack while staying put. Do not go beyond the gate. When your pet dies, run back away from the gate again until it closes again. Then repeat as many times as needed until the dog finally dies.
Spells that can be cast through walls (such as eruption, plague, squall etc.) works very well with this strategy. I killed Cerberus with my pyromancer this way using Core Dweller and eruption. |
