(Original Concept by Lindley Court)
Primary Class: Bloodrager.
Secondary Class: Alchemist.
Hit Dice: d10.
Bonus Skills and Ranks: The depth charger may select three alchemist skills to add to her class skills in addition to the normal bloodrager class skills. The depth charger gains a number of ranks at each level equal to 4 + Int modifier.
Weapon and Armor Proficiency: The depth charger is proficient with all simple and martial weapons, light armor, medium armor, and shields (except tower shields). A depth charger can cast bloodrager spells while wearing light armor or medium armor without incurring the normal arcane spell failure chance. This does not affect the arcane spell failure chance for arcane spells received from other classes. Like other arcane spellcasters, a depth charger wearing heavy armor or wielding a shield incurs a chance of arcane spell failure if the spell in question has somatic components.
Bloodrage (Su): This is exactly like the bloodrager’s bloodrage ability, except that the depth charger gains a +2 bonus to her Strength and Constitution instead of +4. This increases to +4 at 11th level, and +6 at 20th level. This alters bloodrage, greater bloodrage, and mighty bloodrage.
Blood Alchemy (Su): At 3rd level, a depth charger gains the alchemist’s alchemy ability. She can create mundane alchemical substances such as alchemist's fire and smokesticks. When using Craft (alchemy) to create an alchemical item, a depth charger gains a competence bonus equal to her class level on the Craft (alchemy) check. In addition, a depth charger can use Craft (alchemy) to identify potions as if using detect magic. She must hold the potion for 1 round to make such a check.
At 5th level, a depth charger can also channel her bloodrage to fashion magical potion-like extracts in which she can store spell effects. When creating an extract, she can infuse the concoction with a tiny fraction of his own magical power—this enables the creation of powerful effects, but also binds the effects to the creator. By expending two rounds of bloodrage and an unused 1st-level spell slot as a full-round action, she can create an extract of any 1st-level bloodrager spell she knows. This functions as an alchemist extract with a caster level equal to her bloodrager caster level. At 8th level, she can expend four rounds of bloodrage and an unused 2nd-level spell slot to create an extract of any 2nd-level bloodrager spell. At 11th level, she can expend six rounds of bloodrage and an unused 3rd-level spell slot to create an extract of any 3rd-level bloodrager spell. At 14th level, she can expend four rounds of bloodrage and an unused 4th-level spell slot to create an extract of any 4th-level bloodrager spell. This ability replaces blood sanctuary.
Spellcasting: A depth charger adds the following alchemist extracts to her spell list at the indicated spell levels: 1st level–crafter’s fortune, detect metal, detect secret doors, expeditious retreat, heightened awareness, line breaker; 2nd level–air step, alchemical allocation, darkvision, perceive cues, spider climb, transmute potion to poison; 3rd level–absorb toxicity, amplify elixir, bloodhound, thorn body; 4th level–darkvision (greater), death ward, echolocation.
Deep Charge (Su): At 6th level, a depth charger can expend two rounds of bloodrage as a standard action to make an immediate charge attack. When making a depth charge, she gains a bonus to attack and damage rolls equal to twice her highest level of spells she can cast. For example, a 10th level depth charger can cast 3rd-level spells and gains a +3 bonus to her charge’s attack and damage rolls. This ability replaces the bloodline feat gained at 6th level.
Charge Mastery (Su): At 7th level, when a depth charger makes a charge, she can move an additional 10 feet further than normal. This increases by an additional 10 feet at 13th and 19th level. At 10th level, she can make up to two 90 degree turns while making a charge. At 16th level, she can break through solid objects with a hardness of less than 10 and less than 15 hit points when making a charge. This ability replaces damage reduction.
