Is your feature request related to a problem? Please describe.

Currently in late endless runs, combat starts turning into hit the button and walk away to make coffee while all the messages play, even on the highest speed setting. Some amount of the messages are unique can't be easily merged together, but the boss bar stat boost messages are a solid portion of the mini-movie that plays on every metal burst hit and can probably be condensed a bit.

Describe the Feature

Instead of

Eternatus's attack rose!
Eternatus's defence rose!
Eternatus's attack rose!
Eternatus's spatk rose!
Eternatus's spdef rose!
Eternatus's attack rose!
Eternatus's attack rose!
Eternatus's attack rose!
Eternatus's attack rose!

collect the stat changes and condense them into one message.
