Underrated spell.
It has two main uses: to block enemy walkers from going down a narrow path, and to protect shooters from attacks.
The latter capability can be VERY useful against the AI in certain situations if you have a large stack of shooters (Titans being the most obvious). If you place them in the upper left corner, you can cover the Ammo Cart as well with the Force Field, and if you are facing 2-hex non-ranged enemies who are slower than you (or can be made slower by Haste, Slow, and/or Prayer), you cannot lose even against a much superior force. A human opponent of course would be able to circumvent your plan in a number of ways...
Note: Spell duration is NOT increased by any of the spell-duration boosting artifacts (Ring, Collar& Cape of Conjuring).
