Attack

TODO:

conflicting info. manual says:

• 1d20 + ${WEAPON_PROFICIENCY}
• 1d${WEAPON_TYPE_DICE} + ${WEAPON_PROFICIENCY}

at least one profficiency increases on level-up, is this the weapon-profficiency?

Weapon Type

MELEE: <= 5ft
RANGED: any

# class proficiency is your level-proficiency applied to your class's proficiencies.
# Exceptions apply for multiclass characters.
CLS_PROFICIENCY_MOD = LVL_PROFICIENCY if CLS_PROFICIENCIES.include?(WEAPON)

# STR: melee, thrown
# DEX: melee(finesse-weapons), ranged, thrown
ATK_MOD = DEX_WEAPON ? DEX_MOD : STR_MOD

# Final attack value
ATK = ? + ATK_MOD + CLS_PROFICIENCY_MOD

Defend

ARMOR_CLASS = 10 + ${DEX} # + ARMOR
