ABMTAKOPAAPI means "A Boss Mod That's Also Kind Of An API". V1.0.0 adds the first included boss, called "Altuda". The last few words of the name (A Boss Mod That's Also Kind Of An API) are because... multiple reasons, mainly that it's fully customizable, even if it's not TECHNICALLY an API. Altuda is a fairly easy boss if fought in a certain way, otherwise Altuda is very difficult.
When a player first logs in to a new world, they will receive a Start Book containing a hint about how to beat Altuda, as well as where to find Altuda. The giving of the Start Book to new players is toggleable in config. Open the Start Book by putting it in your offhand.
ABMTAKOPAAPI is released with Public Domain license, so changing the loot pools / textures doesn't necessarily need a Data Pack / Resource Pack.

V1.0.0
Released
V1.5.0
Added a new included boss: Posaq. Posaq is found underwater in the ocean. Posaq has a strong melee attack, immunity to arrows & tridents, and has no visible bossbar. Posaq will drop their trident on defeat. As an optional challenge, players near Posaq with Bad Omen will get Current Omen, when that expires Posaq gets boosted swim speed.
THIS MOD IS OFFICIALLY COMPLETED. I WILL NOT FURTHER DEVELOP IT MYSELF.
