Boosting patrols?

[Gregstrom]

The Eye of Accuracy will make a commander better at patrolling. Not much better, admittedly.

Edit: this is not a serious suggestion. You'd be paying 5 air gems for a quarter point of patrol strength.

Ring of Warning gives you a patrol bonus along with being able to have 5 extra body guards (for a total of 10).

Why waste gems on patrolling? Just buy more troops. Or if you want to spend gems to patrol, just summon some blackhawks.

I am not saying that its a great investment .... but every now and then having a couple of rings floating around could come in handy when an opponent starts spamming assassination spells at your difficult to defend mages.
