Astral Bombardier (Summoner/Alchemist)

On other planes, nature and magic combine to produce bizarre creatures with incomprehensible self-destructive capabilities. Astral bombardiers are innovators who weaponize these creatures, calling them to the Material Plane and enhancing them with yet deadlier explosive capabilities. Rather than utilizing an eidolon primarily as a companion or bodyguard, the astral bombardier employs his eidolon as a walking bomb. Using a mixture of alchemy and the summoning arts, the astral bombardier gradually improves upon his formulae, brewing more potent extracts and making his eidolon's explosions more and more deadly. (Original Concept by Flak)

Primary Class: Summoner.

Secondary Class: Alchemist.

Alignment: Any.

Hit Dice: d8.

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

Weapon and Armor Proficiency: The astral bombardier is proficient with all simple weapons, and with light armor, but not with shields.

Brew Potion: At 1st level, astral bombardiers receive Brew Potion as a bonus feat. An astral bombardier can brew potions of any formulae he knows (up to 3rd level), using his astral bombardier level as his caster level. The spell must be one that can be made into a potion. The astral bombardier does not need to meet the prerequisites for this feat. This ability replaces cantrips.

Exploding Eidolon (Su): At 1st level, the astral bombardier infuses his eidolon with volatile arcane substances. When the astral bombardier's eidolon would be sent back to its home plane due to death, it departs with a humongous alchemical explosion. All creatures within 10 feet of the eidolon take fire damage equal to 1d6 + the astral bombardier's Intelligence modifier. Affected creatures take only half damage on a successful Reflex save (DC = 10 + 1/2 the astral bombardier's level + the astral bombardier's Intelligence modifier). The damage from this ability increases by 1d6 points at every odd-numbered astral bombardier level. If the astral bombardier's eidolon is Small, reduce the blast radius to 5 feet; if the eidolon is Large, increase the radius to 15 feet; if the eidolon is Huge, increase the radius to 20 feet.

An astral bombardier's eidolon rejuvenates quickly on its home plane. Once per day per astral bombardier level, he can summon his eidolon even if it died that day. This ability replaces summon monster and gate.

Extracts: At 1st level, an astral bombardier gains the alchemist’s extracts ability, and adds the following spells at the indicated spell levels to his formulae list: 1st level–summon monster I; 2nd level
