Basic Information [Source]

Scaling determines how much additional damage a weapon deals. A character gains a percentage of the weapons base damage as additional damage, indicated by a "+" next to the weapons base damage.

Scaling Values

Letter Grade	Min. %
S	100	The weapon's stat bonus, indicated by a letter grade of S / A / B / C / D / E, and the character's stat's current level each correspond to a percentage value. These are multiplied together and against the weapons base damage to determine the bonus damage received. The letter grade represents a range of percentages.
A	81
B	61
C	45
D	?
E	?

Exact Values

The character's stat is converted to a percentage value. The % values have been rounded.

Stat	%	Stat	%	Stat	%	Stat	%	Stat	%
0	0	20	35	40	71	60	88	80	94
1	1	21	38	41	72	61	88	81	94

17	26	37	67	57	87	77	93	97	99
18	29	38	68	58	87	78	94	98	100
19	32	39	70	59	88	79	94	99	100

These 2 values are then multiplied together, and against the weapons base damage. This is done with every stat that has a scaling value.

Example: a character with 50 Strength and 20 Skill is using a +10 Whirligig Saw which has a base damage of 190, a strength scaling of S (equal to 110% in this case) and a skill scaling of D (equal to 30% in this case). According to the scaling chart, 50 Strength gives 85% of the weapons scaling bonus. So the player gains 110%*85%=93.5% Strength bonus scaling. The weapon has a base damage of 190, so the player gains 190*93.5%= 177 bonus damage from strength. The player also gets 30% (from the D scaling)*40% (from having 20 skill)*190 (base damage)=22.8 bonus damage from skill scaling.

Notes

Soft Caps: Looking at the scaling bonus chart shows that the player gains ~.5% extra scaling bonus for every level until 10, ~3% extra scaling bonus for every level from 11 to 25. ~1.4% extra scaling bonus for every level from 26 to 50~.3% scaling for every level after that. This means that leveling past 25 gives slightly reduced bonuses, and past 50 gives severely reduced bonuses; to the point that putting in extra levels past 50 usually gives less bonus damage than leveling a <50 stat, even if the desired weapon has very low scaling. Here is a Google Doc that calculates the scaling bonus for various weapons and stats.
