Currently, withdrawing from the mist well will fill up one's mist bar with no choosing on the amount of mist withdrawn.
However, there are many times where we don't need the full 100 mist. Sometimes, we just need an extra 10-20 mist so that we can travel further 1-2 depths in the clockworks.
Please give us the option to choose what amount of mist we draw from the mist well. Thank you.
Does it really matter? You don't have to use all of the mist at once, ya know.
