I'm taking a new loremaster through the intro and hope to play this one up through the quests, (my other loremaster on Imladris was built to be a crafting toon, so I haven't really done much else with her).

I've never really done much with the loremaster class before, so I'm pretty new at it. I was wondering how does one activate flanked? I noticed on the sign of battle: wizard's fire, that if flanked is activated when using it, that it also provides some morale recovery. Is there a way to activate flanked or is it completely random?
