View source for Player Modifiers

{{V|1.2.2}}
'''{{PAGENAME}}''' are various bonuses and penalties that are received from a number of different sources such as {{Icon|Mastery}}, [[Equipment]], [[Pets]], and {{Skill|Agility}} obstacles.

==Mechanics==

Modifiers of the same kind stack additively. For example, if a player who has unlocked {{PetIcon|Ty}} (+3% Global Mastery XP) and is wearing an {{ItemIcon|Ancient Ring of Mastery}} (+7% Global Mastery XP) will receive a total of +10% Global Mastery XP.

Any penalties are subtracted from bonuses of the same type to get the total modifier. For example, if the above player also constructs a {{AgilityIcon|Water Trap}} obstacle (-6% Global Mastery XP), their Global Mastery XP modifier will instead be +4%.

===Additive vs Multiplicative===

When describing how different bonuses stack, the terms 'additive' and 'multiplicative' are often used to explain how to combine them.

When two bonuses stack '''additively''', the combined bonus is the sum of the first bonus and and the second bonus. For example, if a +10% bonus and a +20% bonus stack additively, the combined bonus will be +30%.

<math>\small{\begin{aligned} \text{Additive Bonus} = \text{Base Value} * (1 + (\text{Bonus 1} + \text{Bonus 2}) / 100)\end{aligned}}</math>

When two bonuses stack '''multiplicatively''', the combined bonuses is instead

<math>\small{\begin{aligned} \text{Multiplicative Bonus} = \text{Base Value} * (1 + \text{Bonus 1} / 100)  * (1 + \text{Bonus 2}/ 100) \end{aligned}}</math>

If the same +10% bonus and +20% bonus stack multiplicatively instead, the combined bonus will be +32%. If both bonuses are positive (or if both are negative) and they stack multiplicatively, the combined effect will be larger than if they stacked additively.

===Combining Similar Modifiers===
When multiple modifiers affect the same stat, they are usually applied additively. In particular, more specific versions of a bonus will stack additively with the global version of that bonus. 

An example of this would be the Global Mastery XP and Skill Mastery XP modifiers, so a player wearing an {{ItemIcon|Ancient Ring of Mastery}} (+7% Global Mastery XP) who also has reached the [[Agility#Mastery Pool Checkpoints|10% Mastery Pool Checkpoint]] for {{Skill|Agility}} (+5% Agility Mastery XP) will receive a total of +15% Agility Mastery XP.

This also applies to combat modifiers of the same type such as Ranged Accuracy Rating and Global Accuracy Rating.

Nearly all buffs in the game stack '''additively'''.
