For many maps I find that a Shaman Non-Spawning Ground/Shaman Non-Spawning Ground (or option) is needed, badly.
Because, cloud just doesn't do it, as it may make Shaman not be able to summon/spawn to stuff there, but no objects can pass through it anyway.

So a Shaman Non-Spawning Ground would disallow a shaman to summon from there. However, objects can still pass through it if you didn't spawn it there.
This would be INCREDIBLY helpful for survivor, mechanism maps, and pretty much any maps with a shaman, especially if you need to make the map harder.

Otherwise, you could just simply add a "No-Summoning" option. In which it changes to disallow the shaman to summon there. Then, you can disable or enable any of the other options you want to enable/disable. You could make this for only Circle/Rectangle.


I had no space to make it well, but here is a close enough thing, you can format it however you want.
