That's another one for the team.

We've got four.

Oh yeah I forgot to do this...

1) How many waves do you guys would like to face? (5-25)

2) The arena shall be a huge throne room with four pillars lining each side so total of eight pillars. Entrances of the enemies shall be the main entrance and two entrances on each side so total of five entrances. Plus the roof.

Are you guys okay with this arena or do you have a better place in mind?
