Precise

Precise is an Invention perk that increases the minimum hit of an ability by a percentage of its max hit.

Useful information
An ability like Havoc has a 20% - 100% damage range. Its minimum to maximum damage range is realistically 25% - 125%.

However it can be calculated as 20% - 100% because the percentage range ratio is 1:5.

Typically ability damage ranges from 20% to 100%. The table above applies to most abilities except Bleed abilities.

For abilities like Slice where the damage range is 30% - 120%, the "average hit increase" changes, as the ratio of the ability damage range is 1:4 instead of 1:5 for most abilities.

The table below lists Average hit increase of abilities that have a different ratio of ability damage.

Calculation (Formula)
Average hit formula for abilities:

without precise:

$$\frac{M + m}{2} = a$$

With precise:

$$\frac{M + (m + (r \cdot 1.5% \cdot M))}{2} = A$$

Average hit increase formula:

$$\frac{A - a}{a} = a_{increase}$$

Example:

Average hit increase for Slice (Damage Range 30% -120%) with precise 5:

$$a = \frac{120% + 30%}{2} = 75%$$

$$A = \frac{120% + (30% + (5 \cdot 1.5% \cdot 120%))}{2} = 79.5%$$

$$a_{increase} = \frac{79.5% - 75%}{75%} = 6%$$


 * m = Minimum ability damage
 * M = Maximum ability damage
 * r = rank of the precise perk
 * a_{increase} = Average hit increase
