BatoForge analysis // Bugfixes

What this update means for your run

Demo 0.5.4 fixes ongoing abilities that stopped updating during battle after the previous performance work. Fumungus is the example named in the announcement.

  • In an affected older battle, changing conditions could leave the ongoing effect stuck at its previous state. The hotfix restores those updates.

Before using an older guide

An old Fumungus example with an unchanging ongoing effect may show this regression. Use the current ability and changing battle conditions when working out its effect.
