I feel in it’s current form, it is prone to misclicks and costing factions the game unfairly. As it is now, the next time you vote, your vote counts for two. However, if you unvote/vote elsewhere for any reason, the ability is lost and enters a 1-day cooldown.
I feel it could be changed to the following:
Royal Finger - (Unlimited use, 1 day cooldown) - Your Vote will count for 2 for the rest of the day
If that is too strong…
Royal Finger - (unlimited use, 1 day cooldown) - Your vote will count for 2 until a trial begins or the rest of the day
