QoL -Add opacity slider for all Spells

Almost 90% of the times I die is because there's so much stuff happening I can't see a basic enemy Death-DoT and kills me when I'm surrounded by my spell effects (like firewall, minions, etc) . Please fix this for the love of god. Game is amazing but this visual clutter deaths are too punishing when I'm using for example t15 waystones with insane rolled affixes. TYVM.
