Descent: Сказания тьмы

You can perform up to three actions: one maneuver and two others of your choice, in any order. You may repeat an action, including maneuver; you can also take actions between spending movement points (pp. 8, 32).

Spaces sharing a border or corner are adjacent, so diagonal movement is allowed. Becoming adjacent to an enemy makes you impeded: you lose all remaining movement points, and later maneuver actions give you only one movement point while you remain impeded (pp. 8–9).

No. If you move into or adjacent to a space with a sight token, you must activate it immediately, but it does not use an action (p. 9).

You need both range and line of sight. Figures do not block line of sight, but map edges and blocking terrain do; ordinary weapons can attack adjacent enemies, while ranged weapons use their range value (p. 10).

No. Place one fatigue token for each advantage you convert, on a card with a fatigue limit and without exceeding that limit; during the Darkness Phase, each hero can discard one fatigue (pp. 14, 18).

No. Flipping a card discards all tokens on it, including beneficial condition tokens (pp. 13, 20, 30, 32).
