Boromir catches the 'wand' part, which gets a small pause of...mild surprise, but not the bad sort. He's not met any magic users in Baedel yet, so that more or less leaves Gandalf by way of comparison. Enjoy that. "I've met some likely to wield all three. Besides which, I feel I'll have to acquire some new skills myself. This city is different from what I'm used to in most respects."

Given he can usually be seen sporting a sword and cloak, the latter being an elven one to boot, it's not much of a surprise for most people.
