Fixed the Might Ring issue.
Yeah I think it's very useful to know, and very easy to implement as well. Even though exp per stamina hour often is fairly similar to Tibia's built-in counter it is important to observe it directly in order to promote awareness of stamina preservation. For example, if you make a Carlin Dragons script, should you refill in Carlin or Kazordoon? The spawn is at roughly the same distance from both towns, but if you refill in Carlin you're going to have to kill some bugs in the Carlin sewers 90% of the time. This will waste 2-4 minutes of stamina per refill which is really bad, so you should refill in Kazordoon. Similarly it's important to disable targeting when refilling after leaving the spawn in order to avoid killing random monsters on the way back.
