Brandon: I think the shadow is air unblockable. People usually poke or jump in the air to dodge it but can't. I've seen lots of people block it on the ground tho.
CX805: There are plenty of modifications throughout the 3 moon styles, most of which are on Full Moon. I'll try my best to explain it to you.
Crescent/C-Moon system:
- 300% to Max Heat
- You can activate heat before you reach Max Heat but you must have atleast 100% meter to do it.
- If you activate heat during Max Heat, you enter Blood Heat which means your health will generate faster.
- Time stops when you are in either Heat or Blood Heat, not Max Heat.
- Use of Shield/EX Shield mechanics. Only moon to have EX Shield.
- Circuit Spark is manual and must be used when in Max Heat.
Half/H-Moon system:
- 200% to Max Heat (which is just Heat in this system)
- Heat is automatically activated when you reach 200%. If you are knocked down by the time you reach 200%, it will go into heat when you get back up.
- There is no "burst" effect when you heat. This is replaced by auto circuit spark.
- No Blood Heat mode.
- Use of 5a6aa strings for all characters.
- Auto Shield counters. A invincible move comes out after your shield automatically and from there you can combo from it. (Can you hold the counter from coming out?)
- You automatically circuit spark when you are hit in Heat Mode, which ends Heat.
Full/F-Moon system:
- 300% to Max Heat
- Heat can obtained before Max Heat, but it must be done through a canceling of a move which is called Initiative Heat. This is somewhat the Roman Cancel of the game.
- When you reach Blood Heat, all of your red life is recovered at that moment. Downside is that the clock does not stop in this Blood Heat.
- Auto Shield counters just as in Half.
- You can circuit spark manually just as in Crescent.
- You can not Reverse Beat in this system, which means you obey the button order A>B>C for combos and strings.
I may have missed a few things, but this is most of it.
