The Ulter Precisionist

A precisionist  seeks to optimise every facet of their equipment through all possible means. Whether this is sharpening a blade to the thickness of a hair, adjusting the straps on their armour to allow for maximum mobility and range of motion or refining a potion recipe down to the nearest pinch of each ingredient. The precisionist seeks to improve and refine whatever is placed in front of them, they seek to do more with less and are on a journey to learn as much about the mechanisms behind the world as possible.

Tool Proficiency

When you adopt this specialization at 3rd level, you gain proficiency with tinker's tools. If you already have this proficiency, you gain proficiency with one other type of artisan's tools of your choice.

Spellcasting

Starting at 3rd level, you always have certain spells prepared after you reach particular levels in this class, as shown in the Precisionist Spells table. These spells count as artificer spells for you, but they don’t count against the number of artificer spells you prepare.

Refinement

Refine an existing item by collecting materia and ephermia.

1. Materia: Physical items to a total value equal to that of the rarity of an item (i.e. common, uncommon, rare, very rare, legendary, artifact)
   • Refined materials (iron ingots, silver ingots, gold ingots, polished wood, polished gems etc.)
   • Monster parts (hides, chitin, poison gland, alchemical organs etc.)
2. Ephermia: Magical items to a total value equal to that of the rarity of an item 
   • Magic items (pearl of power etc.), this is equivalent to value of item sacrificed.
   • XP from monster kills (whatever xp is gained half the total group value is added to ephermia )

Max number of refinements per an individual item is 3 at level 3, increasing to 4 at 7th level, 5 at 11th level, 6 at 15th level and 7 at 19th level.

Ephermia Efficiency

At 5th level the amount of ephermia gained from monsters is increased. 

Ephermia is gained at a rate of half of the total group experience. Ephermia efficiency increases this by 5% multiplied by half the character's level rounded down.

i.e. Ephermia Modifier = Half Group EXP gained + (Half Character's Level Rounded Down * 5%)

ex. CR1 monster, PC at level 5 = 100 exp, Ephermia = 100 x (0.5 + (0.05 * (5/2)))  = 100 * (0.5 + (0.05 * 2))  = 100 * (0.5 + 0.1) = 100 * 0.6 = 60 ephermia

ex. CR1 monster, PC at level 10 = 100 exp, Ephermia = 100 x (0.5 + (0.05 * (10/2)))  = 100 * (0.5 + (0.05 * 5))  = 100 * (0.5 + 0.25) = 100 * 0.75 = 75 ephermia

ex. CR1 monster, PC at level 20 = 100 exp, Ephermia = 100 x (0.5 + (0.05 * (20/2)))  = 100 * (0.5 + (0.05 * 10))  = 100 * (0.5 + 0.5) = 100 * 1 = 100 ephermia

Materia Reduction

At 9th level the amount of materia required is decreased. 

Materia is reduced at a rate of 1/character level.

i.e. 500GP for an uncommon magic item is reduced to 500/character level, rounded up.

ex. Uncommon Magic Item/Character @ level 9 = 20/9 = 2GP, 2SP, 2CP

ex. Rare Magic Item/Character @ level 10 = 50/10 = 5GP

ex. Artifact Magic Item/Character @ level 20 = 100/20 = 5GP

Time Reduction

At 15th the level the time taken to return infusion slots is reduced as follows:

• 15th level = -1days
• 16th level = -2days
• 17th level = -3days
• 18th level = -4days
• 19th level = -5days
• 20th level = -6days

At minimum infusion slots will not return before a long rest.
