To add on to your note, the only notification we know about Ram's and Dragon's voice are the chimera's eyes. When the text on screen says Chimera's eyes turn violet, you have to run to the boss (close to it, melee range). When the text says Chimera's eyes turn blue, they have to run away from Chimera.

If you run to near max outsides of the arena and Chimera is kept in the middle, you don't need to run into the middle if you're running away from the orb and the Chimera's eyes turn violet. You will be out of range of Dragon's Voice if at the edge of the arena and chimera is left in the middle.
