The Magic Brazier is like the magic lever from the beginner guide. The brazier has many states and casts a spell when it enters each one. But, unlike the lever, the magic brazier has 4 states: off, fire, storm and ice. To change the brazier’s state a player must use the item by interacting with it. This is an advanced trigger, as it requires managing many states that each cast their own spells. The best uses I have seen for this trigger involve creating puzzles. When used with another trigger, you can create a brazier combination to open a door.
