Prized Light isn't a "must have" in my opinion, but it will certainly make trials easier since some units will take less damage.

The Prized Mercy also isn't a "must have", but it is definitely an upgrade from the Malice Jewel as the HP recovery upon getting hit will provide a lot more bulk to your unit.

I bought both, but only because I had the Merit Points to spare. If you're planning on buying one, The Prized Mercy is probably better as the HP upon getting hit can potentially block more damage than nullifying elemental weakness damage. If you can get enough Merit Points, you might as well buy both since Merit Points can easily be earned daily.
