Archetype Features

Powerful Change Level 3

At 3rd level, the brown-fur transmuter learns to harness the power of her magic to empower her transmutations. Whenever the brown-fur transmuter casts a transmutation spell using one of her arcanist spell slots, she can expend 1 point from her arcane reservoir as a free action to bolster the spell. If the spell grants a bonus to an ability score, the bonus then increases by 2. If it grants a bonus to more than one ability score, only one of the ability scores gains this bonus. The brown-fur transmuter cannot expend more than 1 point from her arcane reservoir in this way. This ability replaces the arcanist exploit gained at 3rd level.

Share Transmutation Level 9

At 9th level, the brown-fur transmuter can target others with her transmutation spells. A brown-fur transmuter can expend 1 point from her arcane reservoir to change any transmutation spell with a range of personal to a range of touch. Such a spell automatically fails on unwilling creatures. This ability replaces the arcanist exploit gained at 9th level.

Transmutation Supremacy Level 20

At 20th level, the brown-fur transmuter learns to fully master the power of transmutation. Whenever she casts a transmutation spell, it is treated as it were affected by the Extend Spell feat without altering the casting time or slot used. (She cannot then alter its duration again with the Extend Spell feat). Whenever she uses her powerful change ability, the bonus increases by 4 instead of 2. Her share transmutation ability can now target a willing creature within 30 feet. This ability replaces magical supremacy.
