Medusa shield kills stone units.
Medusa shield is killing Enlivened Gargoyles and Envlivened statues. This is confirmed by the fact that 999 damage appears above their heads. Doing tests, it seems that naturally blind units (fire elementals for example) are the only units not affected by Medusa shield. However, units that become blind from afflictions will be effected by the medusa shield.

Doing more tests, I created a battle with Iron Dragon, Crusher, Enlivened Gargoyle, Golem, Enlivened Statue, and a few other constructs. Some died from the medusa shield, others got killed by the queen.
