I've been meaning to ask this for a while: How do I turn OFF the "Friends Tavern Boost Cost Reduction"? I want to be able to pay full price for my boosts.
Without a boost: Supply Boost 12h (1000 Silver) + Supply Boost 24h (2500 Silver) costs exactly 3500 Tavern Silver.
With my current boost: Supply Boost 4h (233 Silver) + Supply Boost 12h (930 Silver) + Supply Boost 24h (2325 Silver) equals 3488 Silver - LESS than the target, meanign I would need one more boost, or I need to replace the first 4h boost with a more expensive boost.
In other words: Without a boost I can spend exactly 3500 Silver, while with a boost I have to spend more than that. Kinda defeats the purpose of having a boost if I have to spend more.
Learn to find other ways to spend the silver. A simple 15 and 30 minute extra GE turn will be a little over 3500 (or, it is for me right now, perhaps when I hit the next castle level, will have to find another combo). One thing about games - is puzzles! Now this is definitely no kind of a challenge puzzle, but is at its core, a simple puzzle to do.
Next you will be upset that because 2 daily quests in a row asked you to spend silver, but because YOU chose 24hr boost, you will not be happy because you have to wait for the 24hr to expire, and do not feel you should have to pay the diamond penalty to end the boost early.
This game, like so many others, have parameters to play within. Learn to understand them - it will save you further grief in life.
