As I'm about to start running a Viking campaign and one of my players wants to be a rune-carving wizard. The rules are not particularly clear about the rune-carving spells, specially concerning when the spells aren't target at the runecarver himself. What I mean is the caster creates a talisman with Grow Strong (a necklace for instance), so anybody who wears that necklace increase his STR. But there are other spells that works OK if casted as Seidr (Heal Wound, Blunt Weapon, Batlle Fetter,...) but I don't know how those work if used as Rune-carving.
