Mod is inspired by and takes aspects from the "Jojo's Bizarre Adventure" franchise created by Hirohiko Araki.
Mod is an updated version of the 1.6.4 MC version released by (correct me if I'm wrong) "VG" from Korea.

Currently the mod is mostly made up of "stands"; extra entities that when activated provide the player with a bonus. Several items are included that when crafted help provide the player with either a friendly companion to help fight monsters, or the means to obtain their own stand power. Quite basic special abilities are included with the mod separated out to the separate stand powers with many more being worked on. Despite the long time since the previous update the mod is being worked on actively, and has undergone a lot of changes to revamp it. Some such changes are moving away from the hunger system of Vanilla Minecraft. Stand progression is being overhauled so rather than it being the flat exp that is gained, there will be more to this with an emphasis on affecting the stands strength. These features are present in the 0.3 series of updates for MC 1.7.10. These features are being ported up to MC 1.12.2 and will be live in the 1.1 series of updates.

Disclaimer : I do not own Jojo's Bizarre Adventure, I have only updated a mod that is made around that franchise.

Basic Controls :
"V" to summon your stand.
Punch (ie left click) for basic attacks.
Sprint + Punch for different attack / ability.
Sneak + Jump for another ability, sometimes will switch to a different mode. i.e. Crazy Diamond Heal / Destroy, or The Hands scrape / barrage attack.
In the current builds the controls have changed slightly and also rely on activating the powers too. Done with X and C, sneak and these buttons also switch things. Z opens the stats menu.

FAQ - Answers :
- Echoes just goes to Act 1 (0.3 series)
- Hamon and Vampire are basic powers.
- Configs have lots of options for different things.
- Time Stop is disabled and cannot be changed. 0.3.2 has a usable version but buggy, config option.
- "Disc Power" item is used on a gold and iron block for different effects.
- Stand exp gained from having the stand active.
