Something is very FUBAR here. I have one Ice Elemental in defense, and one Spear (called First Blood), yet they fail to load when I get attacked in the city. Highly annoying.

Seems like freeze and tremor "literally" freezes defenders in city as well. This is stupid.
Tremor is bugged as well(1 turn, and it says 3), but I feel that is working like intended, since it has no CD and you can spam it. So update the tooltip
