Oh wait, just remembered. We have this thing too.
Heals injuries, and is recharged by Hysh.
@BoneyM can we hand the Candle to a Light Wizard -- as they can recharge it on their own, since they can just channel Hysh to it -- and ask them to go about providing healing to any humans that need it? (Since, well, magical healing on a Dwarf... I think that starts turning them to stone, or risks doing so. So probably humans only. ... Well, and Demigryphs and giant wolves. But the Amber Wizards might have something for that. Still, couldn't hurt to help the warbeasts too, of course.)
If I remember correctly, neither the Jade Wizard nor any of the Light Wizards on the expedition actually have a healing spell. So our Candle of Cleansing Radiance is it.
Also, fortunately, the Candle is an external item to Mathilde rather than a secret ace like the Seed of Rebirth is! So Mathilde can just hand it out to a Light Wizard, and let them go to town on healing people. Without revealing that she has a secret resurrect-from-near-death ability, if you're worried about that. (Or even better; it makes people think that this is your
only healing ability. Because why would anybody have
two healing items?)
This way Mathilde doesn't have to go around making constant judgment calls on whether to use her limited (but rechargeable) Seed or not. Because the Light Wizard can just easily recharge the Candle natively, via their own ability to channel Hysh.
No need to go about doing
anything, in fact, because this just involves temporarily handing the item over to another person and having them do it; so it can be put into the background (or brought into the foreground if wished).
Neat way to dodge some of the issues of the Seed healing question! ... Or, uh, at least so it looks like to me. Right?
