Rules: "Each time a monster enters a space containing an urn that monster may pick that urn up."
Does it count as an action or not ?
Oath of the outcast - Enc. 1 - Monster picking up an urn - is it action ??
If it doesn't say "as an action" or have an action arrow, I don't think it's an action. It could, however, be a misprint.
Assuming the urn is an objective token, I would tend to think you would have to spend an action to pick it up. Since nothing is specified in the quest rules, I would fall back to the base rules, page 15, which states:
Carrying Objective Tokens
Certain quests allow heroes or monsters to pick up objective tokens. Figures may pick up these objective tokens by performing a special action while adjacent to or in the same space as the objective token ..... A figure can drop an objective token in an adjacent space by performing an action.

Well found, any2cards. This is one of those cases where the tendency to state it explicitly in each of the other quests where the rule comes up makes it less than certain whether this quest is supposed to be different, or the redundant text was just left out. I'd say it's worth asking using the "Rules Questions" link at the bottom of this page.
