Hylaeus

is a pet dog who supports his owner by fetching items. When he is not fetching, he prefers to avoid conflict and initiate combat against creatures that are 2 tiles away from him, compared to most creatures who aggro at 1-15 tiles away. This distance only matters during the initial target choosing.

If Hylaeus has nothing to do, there is a 7% chance every turn for him to search the zone and attempt to fetch an item lying on the ground that the player character would normally autoget, such as ammo or trade goods if those options are enabled within the options. He also has a chance to sniff the air, but this is purely cosmetic.

Pet Response
When pet, Hylaeus either barks, "licks you", "nuzzles you", "puts his snout in your lap", whines, pants, or growls.
