[3.5] Maximum hp possible at 1st level

[Buufreak]

The text doesn’t make an exception for 1 HD characters. Dauntless is a regional feat, and those are limited to one only, taken at first level.

Palanan, you mentioned replacing Toughness with Dauntless for a +2hp net gain. Buufreak suggested keeping Toughness and replacing Improved Toughness with Dauntless instead for a net +4 hp gain.

Let's hope he understands it better coming from you.
