reward for winning Ambush: relentless pursuit

[MalReynolds]

As a reward for delivering the staff to Last Hope, how about giving Relentless Pursuit? It would be just a bit earlier than getting it at the Sun Wall, so it shouldn't really break anything. It just seems strange to hand it over. (And very odd, but that's another topic, that they would just lose it.)

Maybe Sun Wall would then need to give a different reward. Five extra prodigies. No, that's probably overpowered. Maybe a randart, selectable from three. Or Sun Wall could lower the cooldown on RP by one.

Just adding color.
