My idea is to keep subclasssing but let me explain.
My main is a nightblade with herald of the tome and aedric spear. I see my nightblade as a sneakty rogue so bright lights and green beams are not befitting but what if my arcanist beam was shadowy instead of bright green and my templar eadric skills were also more muted in colour ? Just a vague example but you can go tomtown with how creative this could get.
Love to hear your opinions ty
