Envoy: Attribute Boosts

In addition to what you get from your class at 1st level, you have four free boosts to different attribute modifiers. At 5th level and every 5 levels thereafter, you get four free boosts to different attribute modifiers. If an attribute modifier is already +4 or higher, it takes two boosts to increase it; you get a partial boost and must boost that attribute again at a later level to increase it by 1.
