I'd say healing Word. 1d4+Charisma isn't much, but it's a 60ft ranged healing as a bonus action. That will be a life saver if any of us ends up going down, and because it's a bonus action you can still do other important things like fighting. Depending on what Kyra is doing she may not be available for medic duties anyways, so better that we spread potential healing across three (Kyra, Torus, and Parum) instead of leaving it to just a few.
