Question about toughness feat

[swordfish]

So if I pick the feat late in the game, such as at level 10, will I be missing hp points?
Is it worthless unless picked at early levels to not miss the extra 3 hp gain at each level increase?

You will get the full potential of toughness no matter at what level you take it.

It's 3 HP when you first get Toughness then 1 HP per level for every level after Level 3. If you get it at Level 10 you'll get 10 extra HP. If you get it at Level 15 you'll get 15 extra HP, etc.
