Capstan

Selected proud Threlm's Power cannot be used during a Robbing, and you cannot use its special abilities for the rest of this turn

Favour

Capstan is one of four cards in the game that preclude Threlms from providing support during a Robbing (also known as the Divisors), the others being The Wheel, Sextant, and Compass.

Rule Clarification: The effect of this Favour lasts until the end of the turn in which it was played, i.e. it does NOT have a continuous effect.
