Someone seen this error?

[Aprian]

Accession + Barpetrify or Barvirus I do not see the visual effect in the other party member


Manifestation or any Spikes (Blaze, Ice and Shock) same here no see visual effect in the other party member

I can confirm that I've experienced the glitch with Manifestation + Damage Spikes.

I can't speak for Barpetrify or Barvirus, but you should probably submit a bug report here if you want it to be fixed:

I no longer play the game so I can't log on to test them myself. Good luck!
