Druid companion list: Base (1st, aquatic) — aquatic campaigns only

Blindsight (Ex): Porpoises can “see” by emitting high-frequency sounds, inaudible to most other creatures, that allow them to locate objects and creatures within 120 feet. A silence spell negates this and forces the porpoise to rely on its vision (which is as good as a human’s).

Hold Breath (Ex): A porpoise can hold its breath for a number of rounds equal to 6 × its Constitution score before it risks drowning.

Skills: A porpoise has a +8 racial bonus on any Swim check to perform some special action or avoid a hazard. It can always take 10 on a Swim check. *Porpoises have a +4 racial bonus on Spot and Listen checks. These bonuses are lost if its blindsight is negated.

Companion note: A 1st-level druid’s companion is completely typical for its kind. As the druid advances, the companion gains bonus HD, natural armor, Str/Dex, tricks, and special abilities per the Druid animal companion table. Alternative-list animals use the level adjustment in parentheses when determining those powers.
