Houses, Archery ranges, Stables, Monasteries, & Markets can attack adjacent units! Market DPS > skirmisher DPS [test analysis]

• Houses: 5.8 damage/minute

• Archery ranges: 6.5 damage/minute

• Stables: 7.3 damage/minute

• Monasteries, Markets: 23.3 damage/minute

The enemy unit/building has to be adjacent to the building. Which Age you're in appears to have no effect.

All buildings deal 1 damage (regardless of armour). Which means that in certain scenarios against high armour targets Markets & monasteries will have higher DPS than skirms (due to their low attack rate).

Damage appears to be ranged (as rams take 1 damage per attack)

I tested most other common buildings, but they couldn't attack (didn't test towers, harbours, or castles).

Test in HD (although I think it still works in DE):

• have the buildings above each next to an enemy outpost;

• select the building;

• right click the enemy outpost;

• wait 10 minutes in game time.

A FU market can deal 40 damage (135/175) to a battering ram before the market dies.

A feudal age market can kill a watch tower before the watch tower kills it.

Obviously you aren't going to raze the enemy town to the ground with markets (calm down Saracens), but this could be useful to counter enemy towers or forward buildings (especially using the market), or to kill scouts/militias/spears/villagers) attacking your market. Mostly useful early game.

Making the enemy hear the attack sound is good by itself (as it puts them on edge, and they won't be able to figure out what's attacking them)
