DESCRIPTION
Welcome back, Experts- this is the Jungle Altar (35x30), a great place to disrupt a ritual/upset the locals. I'm sure that what they're doing is perfectly legal but if you shouldn't fight them to the death then why is there a battle map for it, answer me that.
Anyway your alternate versions for this one are Magic and Spectral! The Magic variant features your bog-standard magic circle, colored red so you know it's summoning something evil. The Spectral one has ghost orbs and ghost-colored fire, so you know that whatever was sacrificed here had some unfinished business: kicking your ass. Have fun!
