I also would like an alarm to remind me to wipe my rear end when I finish going the bathroom. Seems like a good idea to me as well. As well as if not more practical than your idea, OP.
No support. #gamebraking Also to complicated to implement into the game without throwing all the unbalanced playing into a tornado of hell.
If you mean count how many crystals you've used, that's easy. The op means we don't always know when we can use the next days crystals. If you mean count the hours, does the clock start when you've used a crystal or is there a set time for everyone when the clock restarts?
Simple and useful idea, full support! Came up in the AMA thread as well, should definitely be prioritised over complex and dubious utility ideas.
