Spell schema:
spell: {
name: str internal string name for the spell. Unique identifier, also display
cost: Optional[int] ignored for spells that are not id 1-4
base_spell: int spell index. 0-4 are reserved (0 is melee, 1-4 is common 4 spells)
spell_type: str [TODO: DEPRECATED/REMOVE] "healing" or "damage"
scaling: Optional[str] [DEFAULT: "spell"] "melee" or "spell"
use_atkspd: Optional[bool] [DEFAULT: true] true to factor attack speed, false otherwise.
display: Optional[str] [DEFAULT: "total"] "total" to sum all parts. Or, the name of a spell part
parts: List[part] Parts of this spell (different stuff the spell does basically)
}
NOTE: when using `replace_spell` on an existing spell, all fields become optional.
Specified fields overwrite existing fields; unspecified fields are left unchanged.
There are three possible spell "part" types: damage, heal, and total.
part: spell_damage | spell_heal | spell_total
spell_damage: {
name: str != "total" Name of the part.
type: "damage" [TODO: DEPRECATED/REMOVE] flag signaling what type of part it is. Can infer from fields
multipliers: array[num, 6] floating point spellmults (though supposedly wynn only supports integer mults)
display: bool To show part or not (for some spells there are too many intermediate calc parts). Default: True
}
spell_heal: {
name: str != "total" Name of the part.
type: "heal" [TODO: DEPRECATED/REMOVE] flag signaling what type of part it is. Can infer from fields
power: num floating point healing power (1 is 100% of max hp).
display: bool To show part or not (for some spells there are too many intermediate calc parts). Default: True
}
spell_total: {
name: str != "total" Name of the part.
type: "total" [TODO: DEPRECATED/REMOVE] flag signaling what type of part it is. Can infer from fields
hits: Map[str, Union[str, num]] Keys are other part names, numbers are the multipliers. Undefined behavior if subparts
are not the same type of spell. Can only pull from spells defined before it.
Alternatively, a property reference of the format <ability_id>.propname
display: bool To show part or not (for some spells there are too many intermediate calc parts). Default: True
}
Before passing to display, use the following structs.
NOTE: total is collapsed into damage or healing.
spell_damage: {
type: "damage" Internal use
name: str Display name of part. Should be human readable
normal_min: array[num, 6] floating point damages (no crit, min), can be less than zero. Order: NETWFA
normal_max: array[num, 6] floating point damages (no crit, max)
normal_total: array[num, 2] (min, max) noncrit total damage (not negative)
crit_min: array[num, 6] floating point damages (crit, min), can be less than zero. Order: NETWFA
crit_max: array[num, 6] floating point damages (crit, max)
crit_total: array[num, 2] (min, max) crit total damage (not negative)
}
spell_heal: {
type: "heal" Internal use
name: str Display name of part. Should be human readable
heal_amount: num floating point HP healed (self)
}
