Scythe: Invaders from Afar

After your character ends movement (including after combat or an encounter), Albion may place a Flag token from their supply on that territory; a territory may only have one faction token and Flags may not be moved or removed once placed (page 4).

A Flag counts as an additional territory for Albion at end-game only if Albion controls the Flag’s territory with a character, mech, worker, or an unoccupied structure AND the Flag is not on a territory adjacent to Albion’s home base (page 4).

If an opponent moves onto an armed Trap, the unit’s movement ends, flip the Trap to its disarmed side and immediately apply the revealed penalty if possible (this occurs before anything else, including combat) (page 6).

An opponent may build a structure on a territory with a Trap; at game end, if the only player tokens there are the structure and the Trap, the player with the structure controls the territory (page 6).

No — Trap tokens may not be removed or moved once placed; they have armed and disarmed sides and remain on the board for scoring and interactions (page 6).

Yes — abilities specify their limits: e.g., Toka lets one character or mech cross a river once per turn when moving; Suiton allows movement to/from lakes and grants one extra combat card once per combat on a lake; Ronin grants 2 power before combat when you have exactly one unit; Shinobi allows movement to Trap spaces regardless of distance and has specific arming rules (pages 4 and 7).
