I just found out about Melty Blood a few days ago and just started playing yesterday, so I'm a little unfamiliar with all the terms and commands. I only have the base game, no expansions, and the wiki seems to only talk about the latest expansion/version, and fails to explain which terms and commands pertain to which expansion/version. Specifically, I'm confused on what heat, blood heat, moons, and last arcs are, but some general information too would be nice. Thanks in advance.
