[2021] Arch-Glacor's Core Phase EATS through Armor Spikes.

I'm not sure if this is intentional or a bug, but Armor Spikes Trigger off of Arch-Glacor's Core Phase EATS through the Armor Spikes. But because the Arch-Glacor and its Core are Invulnerable during this Phase, they don't actually do anything.

It would be nice if they actually damaged the Arm as well. It would be a good incentive to use Melee.
