Slow (trait)( Unearthed Arcana, p. 90)
You are slow, but sturdier than average members of your race.
Add +1 to your hit points gained at each level. Drawback: Your base land speed is halved (round down to the nearest 5-foot interval).
You must have a base land speed of at least 20 feet to select this trait. Roleplaying Ideas: Characters with this trait tend to be relatively immobile in combat. They typically prefer to wear strong armor (or other protective devices), since it's hard for them to flee a fight.
