After playing with this idea for a while, I decided to try it. The script below is a random spawner of monsters from a switch statement when you double click on the special brazier. I've always hated the time limit on the deceit brazier, so this one has no time limit. It's not the best and I'm sure there's an easier way to do this, but it's what works for the shard I play on. I'm not a great coder by any means, so all comments, suggestions, and criticism is welcome. Just be gentle, I bruise easily....
NOTE: This code does not contain all the monsters in brittania. It only contains a switch statement of 6 monsters so that everyone can see where and how to add whatever monsters they want on it.
