To those of you not in the TGG discord server (the company making the mobile version of Dominion), the rules for Coffers are getting changed, and this change also requires errata to 2 cards.
The change: You can spend Coffers at any time during your turn.
The reason: The original rule was awful and goes against intuition. How often have you bought a card, and then either realized you didn't spend enough Coffers, or you spent too many?
Side effects include being able to use Coffers to power up action-phase Storytellers, and you can immediately use the Coffers that you get from Spices.
Now there are two cards that need errata because of this. The reasons why is an exercise for the reader (or you can just go to the wiki, where I explained why).
-Merchant Guild: It will give Coffers at the end of your buy phase, and is no longer a dividing line ability.
-Patron: Only gives Coffers during an Action phase.
Also in general "while in play" is disappearing for "this turn." You may have noticed this change has already started with the Hermit
errata I mentioned months ago.
These changes are already on the TGG client, and it'll come to D.G uh eventually. Probably at the same time that the other endless list of errata comes out.
I'm sure someone is going to be sad that a random combo that-comes-up-1%-of-the-time is going to disappear, but I'm not worried about that, and DXV isn't worried either.
