If it's not actually a spell, what was Wanda doing at the end of page 30, and what's with the sparklies around Jillian's head on page 36?
That said, I think that there are aspects to Wanda's influence (i.e. the mundane psychological effects of conditioning Jillian to cultivate and exploit a submissive streak, the "Stockholm Syndrome" effect) that aren't going to just vanish with the breaking of the spell.
Parson's raids destroyed about fifty siege units with attacks from 19 dwagons. Obviously, units can attack more than once per turn.Yes, Jilly's stack is wiping out some dwagons, but if I am understanding the rules of combat properly, a unit can move up to its maximum allotment, and attack once (in whatever order you like -- including Parson's move/attack/move sequence).
