SPECIAL

 stats increase your matching skills and give special bonuses. In Horizon, you start with 29 points to distribute, as opposed to 21 in Vanilla.

Strength
Gives extra melee damage per point, with diminishing returns:

You also gain +10 carry weight with each point, up to a maximum of 300 with 10 Strength.
 * 1-10 Strength = 10% melee damage per point
 * 11-20 Strength = 9%, 8%, 7%, 6%, 5%, 5%, 5%, 4%, 4%, 4%
 * 21-30 Strength = 3%, 3%, 3%, 3%, 3%, 2%, 2%, 2%, 2%, 2%

Perception
Increases accuracy in V.A.T.S

Endurance
Gives 20 health per point (up from 10 in vanilla), but you don't gain health with levelling anymore

Charisma
Starting value for maximum settler population is "20 + Charisma". Settlers are recruited automatically to 10+Charisma.

Dialog speech checks are changed to account for the changes in charisma (and because the default is not very good)


 * No longer should having 8 charisma FAIL on easy checks, and 10 is the maximum needed now
 * You need at least the minimum range listed below to have any chance to pass a check
 * Easy (yellow) = Requires: 2-5 charisma (25%,50%,75%,100% chance)
 * Medium (orange) = Requires: 5-8 charisma (25%,50%,75%,100% chance)
 * Hard (red) = Requires: 8-10 charisma (35%,70%,100% chance)
 * Lady Killer/Black Widow now give +20%/+40%/+60% chance (up from 10/20/30)

REMINDER: Some survival debuffs reduce charisma. Remember this before making incorrect bug reports!

Intelligence
Increases your experience gained by +3% per point

Agility
Affects your sneaking ability and your action points (your total AP is 60 + 10 x AGI).

This makes it useful in combat, so we'd recommend starting with a mid-level score.

Luck
Primarily just affects how quickly you fill the critical hit meter in VATS.
