If
Merry, From O'er the Brandywine (relevant text: While Merry bears a weapon, he is strength +2.) is bearing a hand weapon and skirmishing a minion like
Troop of Uruk-Hai (relevant text: A character skirmishing this minion does not gain strength bonuses from weapons.), does he get the +2 bonus from his ability? I read it as being Merry is getting a strength bonus because of a weapon, but not
from that weapon, though I'm really unsure about that.
Also, I may as well ask while I'm here ... if a skirmish event does not specify a limit on its effect (for example,
Halfling Deftness), does the effect end with the skirmish phase? I'm almost positive it does, but it doesn't hurt to check.
