Actual equations from the contract on the blockchain:
when you attack an enemy your roll gets +7.5% if your weapon element matches, +7.5% if you're attacking the element weak to you, and they stack additively so +15% if both conditions are met
if you attack what you're weak against, it's -7.5% instead of +, so matching weapon+your weak element is neutral, and your weak+nonmatching weapon is negative 7.5%
We don't have the formulas yet (but they've been teased) but we know the general shape of the equation.
CharacterPower + WeaponAlignmentBonus +/- EnemyElementBonusOrPenalty + ([StatBonus*StatBonusMultiplier] * N)
where N is the number of stats
CharacterPower = Power next to the character icon
WeaponAlignmentBonus = "Character and weapon match gives bonus"
EnemyElementBonusOrPenalty = "Character vs. Enemy ... (references the >> diagram)"
StatBonus = Number on the weapon next to CHA/DEX/INT/PWR/STR
StatBonusMultiplier, something like:
- >1 for "Stat element match with character gives greater bonus"
- =1 for PWR
- <1 for ....not match...
