Something strange happened with the armor: it fell to the floor, and a fiery vortex burst out of it, severely burning Sligr (-64 HP). However, the armor didn't move or rise again, which was certainly a good thing.
Feanor tried to attack Cerberus, but it didn't do much, while Cerberus struck back with more force.
