While playing as a pet, could you have it track down a spawn location(s) of a reagent you need. Detection limited to if the reagent does or does not spawn in an area. Also would not ensure that the reagent has not already been harvested by another player. Reagents that are "secondary spawns" or "additional spawns" may not be found by pet. Player could be required to already have a sample for pet to "sniff out".
