Mine Slipway

Rivers have always carried gifts downstream. Not always nice ones.

Launches a mine into the water each time you press its button or it gets an automation signal. Mines drift with the current, faster in faster water, arm after a short while, and go off when they hit something, or at the bottom of a waterfall.

The slipway’s boat also arms Moored Mines within 30 tiles.

A blast

1.6 tiles around, a blast destroys small buildings (4 tiles or less), damages bigger ones and walls, weakens dams, hurts beavers and sets off armed moored mines nearby, which can chain. Roads aren’t hurt.

Mines don’t know friend from foe: they hit whatever they meet, yours and your allies’ too.
