Elemental ArenaIt's back, and we're still working on it. Other thread was too old. The spells used are Amade's Elemental Spell Pack.
Currently features an arena with 3 modes (blocks, water and plain) with a random generator for the blocks. Also features a building where you pick 2 spells (out of 8), a building where you enter the arena. Next to the entrance building there's a building with admin controls. There's also a building where team data is stored (you can group up with friends and create a team to battle other teams). Everything is currently centered around the arena in the middle.
In the future it will feature a store where you can buy headquarters for your team and furniture for it (with money you get by winning battles against other teams). Currently thinking of adding an option to buy a lot so you can build your own headquarters, but it's more expensive. Later it will feature a hall of fame and areas for headquarters (behind the 2 gates that contain the spawns).

The entrance building

The magic guild

One of the rooms of the magic guild, books tell you things about the spell and the open book teaches you the spell (green page to learn, red page to unlearn)

The red gate (which will lead to one of the roads with headquarters) with a spawning garden on the left

The blue gate (will lead to the other road with headquarters) with a small spawning room on the right

The admin control building with buttons that control the arena and entrance building

The shop (not done)
NEW! The lava mode of the arena, designed for long range combat. The lava allows lots of different tactics and it's designed for real matches (2v2 and the like, not FFA)
NEW! The stands on the opposite end from the arena to the arena entrance
OtherIce does not work right now.
Most interiors are bland (focus is on the exterior so the area around the arena looks nice)
