Indicator For Spells Like Sapphire Power

I’m a Mobile player and at work I have to put the game down a lot. When I get back I don’t remember who my targets were, and my combat log is usually a mess since I use lots of “chance to attack”, “cast after attacking” gems.

If an indicator isn’t possible I’m okay with anything else that can help with this. Trying to find the target in the log works, but it’s a frustrating experience.
