The Undertale Effect

By listening to undertale ost's your vrt increases by 100% causing you to get good kovaak's scores. Often people confuse it with 𝓪𝓲𝓶𝓫𝓸𝓽*.

*𝓪𝓲𝓶𝓫𝓸𝓽- a bot that aims.

Me: oh you got a good score on arc dodge switch?
My friend: yeah i used the undertale effect.
Me: oh that makes sense now
