This archetype may be used in place of Sphere Alchemist for meeting prerequisites
Proficiencies: Champion alchemists are proficient with simple weapons, as well as light armor and bucklers. In addition, if this is this character’s first level in any class, they may select a martial tradition of their choice.
This modifies the alchemist’s weapon and armor proficiencies.
Limited Alchemy: A champion alchemist is not able to learn or create extracts, but retains the other uses of the alchemy ability.
This modifies the alchemist’s alchemy class feature.
Casting: The champion alchemist may combine spheres and talents to create magical effects. The champion alchemist is considered a Mid-Caster (Note: All casters gain 2 bonus talents and may select a casting tradition the first time they gain the casting class feature.)
Spell Pool: The champion alchemist gains a small reservoir of energy he can call on to create truly wondrous effects, called a spell pool. This pool contains a number of spell points equal to his level + his casting ability modifier (minimum 1).
This pool replenishes once per day after roughly 8 hours of rest.
Blended Training: A champion alchemist gains 3 talents every 4 levels; the same as he gains caster levels. Whenever he gains a talent he may choose to gain either a magic talent or a combat talent. Champion alchemists use their casting ability modifier as their practitioner modifier.
Greater Training: The champion alchemist may choose to lose mutagen and persistent mutagen to gain a combat or magic talent at every class level with their blended training (instead of 3 talents every 4 levels). He may not take this option if possessing an archetype that would alter or replace mutagen or persistent mutagen
This (optionally) replaces the alchemist’s mutagen and persistent mutagen class features.
