The Weeaboo is an "elite warrior" from a distant land, or that's what he will tell people. He has the power of god and anime on his side so what could go wrong am I right? The weeaboo is a role and luck heavy subclass even among other DnD classes. Will he be brought in as a powerful character or will he be a weakling who can only rely on jokes and that kazoo he bought in middle school?

Bonus Proficiency

When you choose this archetype at 3rd level, you gain proficiency in one of the following skills of your choice: History, Insight, Performance, or Persuasion. Alternatively, you learn one language of your choice.

Power of God and Anime.

Starting at 3rd level, your willpower in battle can shield you and help you strike true. Instead of going unconscious, you can attack once, and max out all roll and damage values. You can move twice the distance at attack at twice the distance. The number of attacks increases when you reach certain levels in this class, increasing to 2 at 10th level and 3 at 15th level.

You can use this feature once per long rest.

M'ladies Man

Starting at 7th level, skill, and careful attention to detail allow you to excel in talking to potential waifus. Whenever you make a Charisma Persuasion check or saving throw, you gain an advantage and proficiency.

Weeaboo Spirit

Starting at 10th level, you may choose to either make one role automatically succeed or gain an advantage on all rolls for one minute.

JJBA Fan

Starting at 15th level, if you take the Attack action on your turn and roll a natural 20, instead of rolling normal damage and doubling it, you may choose to roll five more times and count each one as an extra attack. Rolling another natural 20 restarts the process, adding more attacks. The number of attacks increases to ten at 20th level.

The Dream That Came True

Starting at 18th level, you gain the ability to use a minor version of the wish spell. It is unable to kill anything with a challenge rating over 9th level, and cannot summon monsters or powerful magic artifacts. It can, however, perform wishes such as "I want to have a Hot Loli Waifu" or "I want a sick looking fedora." (To be clear the DM/GM has the final say in what you can wish for.)
