Soulstone alchemist

At 4th alchemist level, you learn the secrets of creating soulstones by experimenting with mana powder. You learn the following alchemical creation:

• Empty soulgem, 4AP - Item. Becomes a propper soulgem when a slain sentient creature dies near one, gaining either a +1, +2, or +3 bonus depending on the creatures age, power, and intelligence ( subject to GM. ) 

You treat all soulgem items (items with the word soulgem) as soulgem items.

At 4th alchemist level, you pay the price of obtaining such a forbidden art. Gain the following:

• -1 max death save slots.

• -1 max HP.

At 4th alchemist level, learn two of the following:

• An arcane cantrip

• An occult cantrip

• A major hex

Use your int or dex as the casting modifier.

At 4th alchemist level, gain 3 of the following upgrades, which are ways in which you can use soulgems, sacrificing them in the process:

• Temporary weapon enhancement - As a full round action, grant a weapon, piece of armor, or tool a bonus equal to the soulgems bonus for 1d4 hours.

• Greater weapon enhancement - During a rest, sacrifice 3 AP and a soulgem to grant a weapon a bonus equal to the soulgems level - 1, and allow it to last 1d100 years.

• Alchemical multiplication - When creating or modifying an alchemical item, duplicate it, creating as many additional alchemical items as the soulgems bonus.

• Alchemical enhancement - Modify an alchemical item, granting it a dice size increase and damage dice increase equal to the soulgems bonus(ex: 1d4 damage > 2d6 damage > 3d8 damage > 4d10 damage.) and durations by that many units (rounds, minutes, hours, or days.)

• Enhanced magic - As a bonus action, upgrade one hex or cantrip that you know as many times as the soulgems bonus. Lasts 2d4 rounds.

• Swap powers - During a rest, spend 1 rest dice and a +2 or greater soulgem to replace a cantrip or hex you know with a different cantrip or hex of their original class (arcane to arcane, major hex to major hex.)

• Learn soulgem magic - As a full-round action, sacrifice a soulgem to learn a spell of a level equal to the soulgems bonus, which the creature who's death powered the soulgem either knew, or has a strong affinity for (Subject to GM.) You can only learn up to as many spells through this method as your int bonus -1 (min 1) and as you learn a spell over the limit, the oldest one is lost. You may spend a number of rest dice equal to the level at which you wish to cast the spell(max 1/2 your level, rounded up) to cast them, using intelligence as your casting modifier.
