Traps, Relics, Shields

A few things added:

Traps are a chance based objective that will deal 10 damage to your expedition if failed.

Shields can be found in chests, they absorb 5 damage.

Relics can be found in chests, some merchants require them and will pay double.

You can now take control of opponent city tiles but it will cost 2 expansion points instead of 1.
