OK, here’s the writeup:
Leopards posess the following racial traits:
- +6 Strength, +8 Dexterity, +4 Constitution, +2 Wisdom, -4 Charisma
- Medium size
- Basic speed 40 feet, climb 20 ft
- Low light vision
- Improved Grab: To use this ability, a leopard must hit with its bite attack. It can then attempt to start a grapple as a free action without provoking an attack of opportunity. If it wins the grapple check, it establishes a hold and can rake.
- Pounce: If a leopard charges a foe, it can make a full attack, including two rake attacks.
- Rake: Attack bonus +6 melee, damage 1d3+1.
- +8 racial bonus on Jump checks and a +4 racial bonus on Hide and Move Silently checks. Leopards have a +8 racial bonus on Balance and Climb checks. A leopard can always choose to take 10 on a Climb check, even if rushed or threatened. In areas of tall grass or heavy undergrowth, the Hide bonus improves to +8.
- Four Feet: A leopard has no fine manipulators and cannot use most conventional equipment. If one leg is injured, the leopard’s speed decreases by one half.
- Animal: As an animal, the leopard is affected by spells such as hold animal. Hold person has no effect. In addition, humanoids who are not aware of the leopard’s intelligence treat it as dangerous, and it has a -4 penalty to all Diplomacy and Gather Information checks.
- Automatic Languages: Sylvan. Bonus Languages: Common, Elven, Gnomish
- Favored Class: Monk
Note that there’s no level adjustment there despite the insane stat adjustments–which are actually rounded down from the description in the MM. This is for a couple of reasons. One, the PC simply can’t use most items, including weapons. Two, the social penalties for being an intelligent animal are pretty heinous, and should be roleplayed out even when there’s no actual die rolling involved.
I was tempted to put in bonus to Bluff, because a leopard doesn’t have facial expressions the same way a humanoid does, and Intimidate, because, well, niiiice kitty. But I’m torn–do we need a trait for female leopard PCs, whereby once every few months they go into heat? I’d expect it from any GM I played with, but it seems like fodder for the idiot gam3rz of the world.
