Besides being Grimbeorn the Old best friend this card is often very useful and has a few nice target. It can help our old friends Beregond/Beregond to be even more of a stone wall, or power-up it's rightful owner Boromir so that it can take advantage of both the boosts (for other heroes except Grimbeorn some form of external readying is required). Satisfying the condition is usually trivial so the boost will be used almost always.
