If the animal fails its saving throw, the ranger has successfully modi ied its behavior. The attitude of the animal shifts one category, up or down, on Table 30 as decided by the ranger. If the animal was Indifferent, it now becomes either Cautious or Friendly, and behaves accordingly. This new reaction applies only to the ranger. An animal that the ranger changed from Threatening to Cautious may still behave in a Threatening manner to other members of the party, particularly if another character decides to interfere with the ranger's efforts or otherwise draws attention to himself. However, as long as the ranger stays near the animal and continues to soothe it, the animal's attention will remain focused on the ranger, and it will remain Cautious. After the ranger leaves the area, the animal's attitude remains altered for a short time (from a few minutes to an hour, as decided by the DM) before it reverts to its original disposition.
If the animal succeeds in its saving throw, it resists the ranger's efforts and its attitude remains unchanged. The ranger notices no significant difference in the animal's behavior. An Indifferent animal continues to ignore the ranger, a Hostile animal may suddenly charge him. The ranger can't make a second attempt to modify its behavior.
This group includes animals that have non-hostile dispositions and are routinely domesticated, such as horses and dogs. It also includes formerly wild animals, such as bears and monkeys, that have been tamed and now are comfortable around people.
Such animals are presumed to be Frightened, Friendly, Indifferent, or Cautious. Regardless of their initial disposition, when a ranger approaches and soothes them, they become Friendly. No saving throws are necessary; this change is automatic. It's also permanent, so long as the ranger stays in sight of the animal. If the ranger leaves the area, the animal reverts to its original disposition a short time later (within a few minutes to an hour).
The attitude change applies to the ranger only; an Indifferent dog feels Friendly to the ranger but remains oblivious to the ranger's companions. A Cautious horse is Friendly to the ranger and will carry him on its back, but bucks furiously if anyone else attempts to mount it.
Additionally, the ranger can ascertain the general qualities of any domestic animal he befriends. By observation alone, he could determine:
Which puppy in a litter will become the best hunter and most loyal companion.
Which horse at a sale is the healthiest, strongest, and fastest mount.
Which sheep in a flock will produce the highest quality wool.
Which sow in a sty will give birth to the largest broods.
The DM should provide any information of this type that the ranger wants to know, though he should refrain from answering specific questions. For instance, the ranger can determine which horse in a corral is the fastest, but he can't tell the horse's exact speed
