Alchemical Blade (Fighter/Alchemist)

(Original Concept by Elghinn Lightbringer)

Primary Class: Fighter.

Secondary Class: Alchemist.

Alignment: Any.

Hit Dice: d10.

Bonus Skills and Ranks: The alchemical blade may select three alchemist skills to add to his class skills in addition to the normal fighter class skills. The alchemical blade gains a number of ranks at each level equal to 2 + Int modifier.

Weapon and Armor Proficiency: The alchemical blade is proficient with all simple and martial weapons, with all armor (heavy, light, and medium), and with shields (including tower shields).

Bonus Feats: This is exactly like the fighter ability of the same name, except that the alchemical blade gains a bonus feat at 1st level, and again at 4th level and every four levels thereafter (8th, 12th, etc.). In addition, whenever an alchemical blade could select a bonus feat, he can choose the Extend Oil or Eternal Oil discovery (see below). These discoveries apply to the alchemical blade’s oils only.

Alchemy (Su): At 2nd level, an alchemical blade can create mundane alchemical substances such as alchemist’s fire and smokesticks, just like an alchemist, but cannot create bombs, extracts, or mutagens. He gains a bonus equal to half his level to Craft (alchemy) skill checks, and can use Craft (alchemy) to identify alchemical items and potions as an alchemist. This ability replaces the bonus feat gained at 2nd level.

Alchemical Pool (Su): At 3rd level, the alchemical blade gains a reservoir of alchemical energy that he can draw upon to mix magical, gear-enhancing oils. This alchemical pool has a number of points equal to 1/2 his alchemical blade level + his Intelligence modifier. This pool refreshes every morning. Creating a magical oil takes 1 minute and expends 1 point from the alchemical blade's alchemical pool. This procedure uses raw materials of insignificant cost and requires that the alchemical blade have an alchemist's kit on hand. An oil created in this fashion grants the affected armor or weapon a +1 enhancement bonus. This bonus increases as the alchemical blade gains levels, and can be added to already magical gear, stacking with existing enhancements to a maximum of +5. Multiple applications of magical oil to the same piece of gear do not stack with themselves; the most recently applied oil takes precedence

At 3rd level, an alchemical blade can create an oil that, when applied to armor, grants the armor a +1 enhancement bonus. For every four levels beyond 3rd, the armor gains another +1 enhancement bonus, to a maximum of +5 at 19th level.

At 5th level, an alchemical blade can create an oil that, when applied to a weapon, grants the weapon a +1 enhancement bonus. For every four levels beyond 5th, the weapon gains another +1 enhancement bonus. This bonus increases again to +5 at 20th level.

As the alchemical blade gains levels, he gains the ability to prepare magical oils that add speci
