I thought it’d be good to have a compilation of all the skills that actually scale thanks to having a percentual modifier in their calculations. At first I just wanted to list all the skill modifiers , listed or hidden, but when figuring out how all of them interacted, I decided to expand upon it.


The Formula

After much testing, and kindly simplified by user Tarocha here on the forums, and another user by the name of KDBA on reddit, damage in Tree of Savior is calculated like this :

(((((Skill Attack + (Effective Attack * (100% - Level Penalty)) + (random(0% ... 100%) * Magic Amplification)) * (100% + Base Modifier)) - (Effective Defense + Elemental Resistance)) * (100% + (0 or 50% if crit)) + (0 or Critical Attack) + Extra Elemental Attack + Enemy Specific Damage) * (100% + Skill Modifier) * (100% + Common Modifier) * (100% + Target Modifier) * (100% + Enhance Modifier) + Bonus Damage

All modifiers are converted from total figures to additive figures for the formula. For example, Meteor is 400%, so the additive value is +300%. All modifiers within a same tier are additive to one another and are added to the default value of “100%”. Here’s a list of all the existing modifiers (and related formulas):

Effective Attack
Your attack power after any modifiers. Usually this is just the value in your F1 Character Window, and as such, anything that visually updates that window wont be listed here. There are modifiers that alter the base attack stat in some way without showing this in the character window however. They can both be flat values or percentual modifiers. Examples are Pommel Beat on stunned targets, Cloaking’s attribute, or Shield Charge.

Level Penalty
When you’re more than 5 levels below an enemy, a penalty will start decreasing your attack in relation to the level of the enemy you hit by 2.3% per level past 5 levels, so 9 levels below is 2.3 * 5 = 11.5% decreased attack versus that monster.

Skill Attack
Easy, the raw value listed on the skill’s tooltip. Very few things modify this directly, but there’s a few, such as Effigy and Cassis Crista.

Magic Amplification
This is a very simple stat. It acts like a “Maximum attack” range for magic attacks and that’s pretty much it (on top of, of course, existing “Maximum Attack” increases. It’s still a different stat). It randomly adds between 0% and 100% of your Magic Amplification to your attack.

Base Modifiers
These modify the total damage a skill would do before defense is subtracted. They are quite potent, as they can cause your damage to vastly exceed an enemy’s defense and create a much larger number for the rest of the formula to calculate with.
Modifiers like this include Split Arrow’s “Bounced Arrow Attack”.

Effective Defense
The defense of the enemy after any modifiers are applied to it. When no modifiers are in effect, this is simply the defense of the monster. The defense modifiers can be both flat values or percentual modifiers. The order these debuffs are applied in only matters based on the final debuff applied. If the final debuff was a flat reduction, it does that last, applying any percentual modifiers first.

(Defense * Percentual Modifier) + Flat Modifier

If the final debuff was a percentual reduction, it does that last, applying any flat modifiers first.

(Defense + Flat Modifier) * Percentual Modifier

Elemental Resistance
If a monster has any (usually this is only through Resist Elements), it will be added here when you cast an attack with the respective element. For example, if you have 100 Lightning Resist, only Lightning-based skills (Electrocute and Zaibas) will add said Lightning Resist to your defense when they are used on you. Simple non-elemental attacks but where the attacker has “Lightning Attack” stats are not added here, but along with the Lightning Attack value itself further into the formula. See “Extra Elemental Attack” below.

Critical Hit
When you land a critical hit, you simply add 50% to the formula above and then add your Critical Damage. As magic can’t crit, this will just always be +0% + 0 for those skills. Sorry mages!

Extra Elemental Attack
This is where all your Elemental Attack stats are added, after crits, before everything else. These all add on to each other if you have multiple types of elements and are always applied, no matter what the attack is (even on DoT effects like Bleeding!).
This Elemental Attack is already multiplied by Elemental Bonuses on its own, so yes, having Fire Elemental Attack and then casting a Fire skill on a Ice enemy will make it multiply by 150% once for itself, then again for the whole skill.
Elemental Resistances and Resistance buffs/debuffs are accounted for again here too, just like the bonus being applied twice. The full formula for Elements is :

((Elemental Attack - (Elemental Resistance +- Modification)) * Elemental Modifier) (+ ...)

Where (+ …) is a repeat of the first part for every element you have Elemental Attack for.

Enemy Specific Damage
You know the ones. Additional damage to Beast-Type enemies and the like. Very simply added straight on here, after crits, before everything else, just like Elemental Attack.

Skill Modifier
These are the modifiers that are directly listed on the skill tooltips right in front of the skill’s raw attack value.
Modifiers of this tier include Meteor, Stone Shot, and Claymore.

Common Modifier
The main bulk of the modifiers. A lot of things in here will end up being added together in the game as they are rather common.
Modifiers of this tier include Elemental Properties, the Missile penalty, hidden modifiers like Ice Bolt and Cartar Stroke, certain attributes like Quick Cast : Magic, and so on.

Target Modifier
The modifiers here are all dependant on what you hit, what type of attack you hit it with, and so on. This includes all of the Armor-type modifiers, but also some Size-related modifiers and certain attributes There’s no real distinction between these modifiers and common modifiers, I just had to come up with something to seperate them :wink:

Enhance Modifier
While this mainly includes the obvious “Enhance” attribute almost all offensive skills have, there are a few outliers that still work additively, such as Fencer’s Aggression attribute.

Bonus Damage
Additional bonus damage. They are just extra damage values that usually even appear as a separate yellow number to tell you they’re there, complete with skill name of what caused it. They never get multiplied and are added way at the end of everything
These include buffs like Blessing and Concentration.
The increase in damage caused by Crossbow Mastery may fall under this category too.

Additional Attacks
“But these aren’t even in the formula!” Well, no, they aren’t, because these pesky little guys have their own very slightly different formula.

(Additional Attack + Extra Elemental Attack) * (100% + Common Modifier + Target Modifier) + Bonus Damage

Very similar isn’t it? You just drop defense, magic amplification, critical hits and all that out of the equation, replacing Skill/Base Attack with the “Additional Attack” from the tooltip.
These hits are caused by buffs such as Enchant Fire and Sacrament.

Enhance Modifiers wont be mentioned here, as they will simply never apply due to only being triggered by normal attacks. (This includes Fencer’s Aggression, which also only affects skills)

Attacks of this type are ALWAYS Magic-type. As such, they will do 50% increased damage against Ghost-armor.

Oddly enough, these attacks add Common and Target modifiers together, causing them to be additive (for example, hitting a ghost / dark monster while sacrament is active)

Pet Mechanics
Pets have their own stats, and for skills or attacks that use these stats, the formula follows the normal one for the most part, with the exception that Base Modifiers and Skill Attack are moved from before defense to after critical.

((Effective Pet Attack * (100% + Base Modifier)) + Skill Attack) * (100% + Skill Modifier) * (100% + Common Modifier) * (100% + Target Modifier) * (100% + Enhance Modifier)

Where Effective Pet Attack

Pet Attack - (Defense + Defense Modifier) * (100% + (0 or 50% if crit)) + (0 or Pet's Critical Attack)

The only known attacks that are based on a Pet’s stats currently are the basic non-skill attack, and Rush Dog.
Snatch, Coursing and Retrieve will use the player’s stats and thus follow the normal formula.

Pet Skills will always do Strike-type damage. A pet’s basic attack is type-less.


If you find anything that does not adhere to the formula I created and others perfected, then be sure to say so! I’ll see what’s up as soon as I can.
Many thanks to people who made rough formulas for a lot of separate things, as well as those who helped simplify it! Sometimes it was just piecing things together.
