Pull and Set Main Character - dentalmisorder/genshin-eremite-discordbot GitHub Wiki
use !pull - to wish for characters and get gacha inside gacha. Different characters provide different buffs, BUT NOTE: Characters provide buff only if he is equipped (!setcharacter [character name]), otherwise he is just a data in your inventory.
after you !pull -ed for some waifus dont forget to use !setcharacter [waifu name] to set her/him into your profile so that people can envy your accomplishments. Also different characters have different profile pictures, you might like some :)
