Some workings stay on the land after the casting, and enchanted ground is marked twice over. On the map, a small wax seal sits on the province: round for a helpful working, torn for a harmful one, with a pip for each season it has left. On the province panel, every active effect is a chip naming the caster and the exact numbers. Nothing lingers invisibly, yours or anyone else’s.
Bless the Harvest. A province of yours gains +6 gold and +3 order each season, for 3 seasons.
Sow Discord. An enemy province suffers −6 order each season for 3 seasons.
Ward of Embers. A province of yours defends +20% for 3 seasons.
Veil of Night. For 2 seasons, every province you rule is +8% harder to attack (confusion in the dark).
Harbor quarantine. Not magic, just misfortune. An event can close a port: −6 gold each season for 2 seasons.
Everything else in the spellbook lands at once and is done: the full list lives in the Emberlight chapter.
