Except that we haven't seen the second Slay, or any summons, from our other 2 games. It's not impossible that Solstice doesn't have 2xSlay and summons, and it's also not impossible that ICE HYDRA has the Frozen Volcano spell.

The game is currently in a deadlock, Radium will definetly not attack, we (I) have already lost part of our initiative by allowing Solstice and ICE HYDRA to defend rather than attacking them immediately, so we must act now. There's nothing else to do.
