I tested out this team in MoC 2.1.2 which is Robin's MoC
The buff:
After every attack launched by an ally, apply 1 stack of Memory Imprint to all allies. Allies in the Memory Imprint state deal 5% more DMG. This effect stacks up to 6 stacks. When Memory Imprint reaches max stacks, immediately regenerate 25% Energy for all allies. The Energy regenerated by this effect can exceed the target's Max Energy.
Remove all Memory Imprints from all allies at the start of every wave or Cycle.
