- Trap - A Transient mine that usually Triggers an Effect once. Surprise!
- Camp - A Transient modifier with limited number of uses. Each use it counts down until it disappears. Counters extend a Property.
- Keep - A Permanent modifier that extends a Property.
- Sync - A Permanent modifier that Triggers duplicate Effects.
(X) Camp N means to Create a Camp Site of the Property Parameter in exactly N TARGET SPOTS. Each Camp has a Countdown that counts closer to zero each time it is used (whereupon the Camp Destroys itself). Camp Sites may also be Razed.
"Camp" by itself means:
Camps have a Countdown X which is positive or negative. Every time the Camp applies its Property, the countdown is moved one closer to zero. If it reaches zero, then the Camp is destroyed. So a -3 Offense Camp becomes a -2 Offense Camp, then -1 Offense Camp, and then disappears. Note this Countdown occurs on application, not by Turn. A Camp that does nothing in a Turn doesn't count down.
Properties without an X Parameter must supply one explicitly. So, for example, an Obstacle (+2) Camp would prevent a Unit from Occupying a Spot twice, then destroy itself. Obstacle (+2) Camp 3 would mean to create three such Camps.
