Understanding Spell Parameters

Each spell slot has these key values:

Parameter	DB Field	Description
Effect ID	effect_id1 - effect_id12	The SPA (Spell Affect) number - what the effect does
Base	base_value1 - base_value12	Primary value for the effect
Limit	limit_value1 - limit_value12	Secondary value, often a cap, type restriction, or spell ID
Max	max_value1 - max_value12	Maximum/cap value, or third parameter
Formula	formula1 - formula12	How the base value scales with caster level

Formula Values (Level Scaling)

Formula	Calculation	Notes
0	base	No scaling
100	base	No scaling (same as 0)
101	base + (level / 2)	Half level scaling
102	base + level	Full level scaling
103	base + (level * 2)	Double level scaling
104	base + (level * 3)	Triple level scaling
105	base + (level * 4)	Quadruple level scaling

Damage Types & Resist Types

Spells have a resist_type field that determines what resistance is checked AND what "damage type" the spell is considered. Many focus effects and limiters use these values.

Resist Type IDs

ID	Name	Description
0	RESIST_NONE	Unresistable (always lands)
1	RESIST_MAGIC	Magic damage/resist
2	RESIST_FIRE	Fire damage/resist
3	RESIST_COLD	Cold/Ice damage/resist
4	RESIST_POISON	Poison damage/resist
5	RESIST_DISEASE	Disease damage/resist
6	RESIST_CHROMATIC	Lowest of MR/FR/CR/PR/DR
7	RESIST_PRISMATIC	Average of MR/FR/CR/PR/DR
8	RESIST_PHYSICAL	Physical resist (rare, see Muscle Shock)
9	RESIST_CORRUPTION	Corruption resist

Using Resist Types in Focus Effects

SPA 135 (LimitResist) restricts which spell damage types a focus affects:

• Positive value = Include only this resist type
• Negative value = Exclude this resist type

Example: A focus that only boosts fire spells would use:

• Effect: SPA 124 (ImprovedDamage), Base: 10
• Effect: SPA 135 (LimitResist), Base: 2 (positive = fire only)

Example: A focus that boosts all damage EXCEPT cold:

• Effect: SPA 124 (ImprovedDamage), Base: 10
• Effect: SPA 135 (LimitResist), Base: -3 (negative = exclude cold)

---

Common Combat Skill IDs

ID	Skill	ID	Skill
0	1H Blunt	1	1H Slashing

7	Archery	8	Backstab

numhitstype	What counts as a "hit"

NumHit Type Values

1	Incoming hit attempts
2	Outgoing hit attempts
3	Incoming spell casts
4	Outgoing spell casts
5	Outgoing hit success
6	Incoming hit success (landing on you)

Notes for Set Bonus Design

Common Set Bonus Patterns:

1. Stat bonuses: Use SPAs 4-10, 159 for stats; 1-2 for AC/ATK
2. Damage bonuses: Use SPA 185 (DamageModifier) with Limit = skill type
3. Crit bonuses: Use SPA 169 (melee), 170 (spell), 273 (DoT)
4. Proc effects: Use SPA 85 (WeaponProc) or 419 (AddMeleeProc)
5. Focus effects: Use SPA 124/125/286/392 with appropriate limiters
6. Survivability: Use SPAs 168 (mitigation), 55/78 (runes), 172-175 (avoidance)
7. Damage type focus: Use SPA 124 + SPA 135 (LimitResist) to boost specific damage types
8. Vulnerability debuff: Use SPA 296 + SPA 135 to make targets take more of a damage type

Tips:

• For set bonuses, create a hidden buff spell that applies the bonuses
• Use CastSpell() from item scripts when set threshold is met
• Use BuffFadeBySpellID() when pieces are removed
• Test stacking with existing game buffs!
• Resist types are damage types - Fire resist = fire damage, etc.
• Use positive limiter values to include, negative to exclude
