Edit : 1.0 -> 1.1

It's a nice place to start, but it really should have more doors. The one entrance it has tends to get camped, so one has to add more, or find another way to prevent the entrances from being camped to make the prefab really useful in a PvP map.

A stylish dome, with a kind of spiral twist to the framework and topped with a circular glass pane. The domes adhere closely enough to a real sphere shape that one can easily position a ZoneManager zone of appropriate radius in the dome so your plugins know when a player is inside, there may be a bit of room at the apex of the dome that remains uncovered by the zone, but that's really not an issue since the chances of someone making it to the inside top of the dome in normal gameplay is basically 0%. 

1.0 -> 1.1 upped the count to 10 variations with varying doors to the dome, vastly increasing the value of this item. If you need a large dome, this is the pack you want.
