Doriki
Doriki is one of the two power levels players and entities have and can get abilities based on.
Doriki allows players to unlock and use Racial abilities, more about them here
Its also used partially in unlocking Haki abilities and improving them
Doriki also increases a user's max health, after 2000 doriki every 40 doriki1 awards the player with 1 extra health point up to a maxmimum of 250 health.
This is a config option and thus could vary from server to server or from modpack to modpack, 40 is the default value, the maximum can go up to every 100 doriki.
How to obtain Doriki
Killing entities is the most sustainable way to gain doriki. Stronger enemies give more doriki while non-aggressive ones will not give anything.
Large amounts of doriki can be obtained by finishing Challenges as well, however there is a limited number of challenges available and doriki is only obtained after the first completion.
Why do I stop gaining Doriki ?
Doriki gains have limits based on how strong the player and its target are, meaning players are unable to farm the same enemy until max doriki. Killing stronger and stronger enemies as the player grows is mandatory.
What mobs can give Doriki ?
Entities from the Mine Mine no Mi mod itself have more or less a set amount of doriki with little variation coming from adding or subtracting random amounts, entities coming from vanilla or other mods (that do not directly support Mine Mine no Mi) however reward doriki based on a "threat" level calculated by their attack and health stats.
