Discussion about the Sanctuary faction.

The troops have a small movement range, and most of their abilities are focused on defense.

You're getting carried away – the upgraded Kappa, when jumping, hits three, or even four, units, dealing significant damage, and the jump covers almost the entire map.
And the freezing of Cryons deals solid damage + counterattack + the enemy loses a turn.
And the attacks of the Four-Armed, especially if it hits two or three times in a row.
And the attacks of the Shark Guards with their terrible wounds.

The Sanctuary is more effective in attack than in defense.
