Serverside logic running on the client

This method is ran on the client and server https://github.com/ProfessorFichte/Elemental-Wizards-RPG-Class/blob/77ef532a37903957106043b7c762dd809e351eb2/src/main/java/net/elemental_wizards_rpg/effect/SoakedEffect.java#L19, yet the ParticleHelper.sendBatches(...) uses a server-side only api. You should check if the entity world is not the client before performing server only logic.
