[Protea] notes and game play style.
Straight away you cast her 4. Temporal Anchor (everything lost is returned) so why not? Plus she gets status immune (no need for [Rolling Guard]) and if she dies she is simply brought back to the same spot.

You should want two amber shards for the casting speed. This is for 25% plus x2 for 50% casting speed.
The other three should ideally be red shards, unless you want to increase health or energy.
