However, it's likely that she'll have to retreat either this turn or the next. The question is whether to skip this turn and start healing on the next, or vice versa. I would suggest retreating now and positioning her under Locken's barrier. Then, from a favorable position, heal everyone.
Reflection seems pointless to me. It won't secure a favorable position, and it will waste a turn.
In general, she should position herself to the right of Castor. That's what I think.
Then, I suggest Locken place the barrier so that Anemone is within it. Having a couple of southeastern skeletons under the barrier isn't a problem.
