1. A truck like that from halo, with a drop ship, this is supposed to be space themed right? Then can it also have sci Fi aspects? Like it could be human technology or even backup to protect school, like agents, or it could be neutral and they are doing research on the area,  and they attack anyone that gets in the way of their research.

2. Vehicles if possible in the future and if needed

3.mana energy flowing from ground, that can be used to make potions as an extra ingredient and can heal anyone using it, it could also boost power.

4.craftable gear or buyable gear

5. Cafeteria for food and drink

6. Pranks like traps and jokes to make it easier to escape enemy.
