Just wondering if I take toughness at level one do I just get the +3hp or do I get the +3hp plus 1 additional HP per HD and since he has two HD at level 1 does that mean 3 + 2 HP for a total of 5? :O could someone provide some clarity on this one.
The Toughness feat reads
Benefit: You gain +3 hit points. For every Hit Die you possess beyond 3, you gain an additional +1 hit point. If you have more than 3 Hit Dice, you gain +1 hit points whenever you gain a Hit Die (such as when you gain a level).
If the animal companion only has 2 HD they would only gain the +3 HP. Once they reach 4 HD they would have a total of +4 HP, 5HD would give them 5 HP, ect. The easist way to think of the feat is after 3 Hit Die/Levels the character gains an extra hit point.
