Half the confusion around buffs comes from the fact that percentages and units are constantly mixed upIn the tables below they are strictly separated:

• Interest — where the game has a multiplier. "Phys. Attack +15%" means your attack is multiplied by 1,15.
• Units without a percent sign — where the increase is flat. "Stun Resistance +40" is 40 points of the indicator, not 40%. The difference is fundamental: resistances are included in the chance formula by subtraction, not multiplication.
• Multiplicity (×3, ×6) — where the multiplier is large and it is inconvenient to read it as a percentage.

A special case - physical crit chanceIt is also set by a multiplier, so "+100%" for Song of Hunter means exactly twice the chance, not "+100 points".

They're applied to one character at a time. This is the basic set a buffer applies before going farming.

Three heavy buffs: Overlord and Dominator. They share a slot with Chant of Victory, Magnus' Chant, and Victories of Pa'agrio—they don't stack.

They are applied to the entire group at once with one click.

Swordsinger and Sword Muse. They last for 2 minutes, but they apply to the entire party and don't interfere with each other.

Bladedancer and Spectral Dancer skills, also 2 minutes per group.

Applies to all nearby clan or alliance members - no need to include them in a group.

Each member of the group is summoned a cube, which acts in battle itself.

They're cast not by the player, but by the summoned creature. The duration increases with its level, with the maximum value shown in the table.

They are attached to your pet or servant, but do not affect the player themselves.

A pet tamed at the Wild Animal Farm can buff its owner. There's usually no dedicated section on this.

They're not tied to a profession: they're earned through status. The last two are an exception to this page's rule: the hero only applies them to themselves, but it's common practice to find them alongside Heroic Valor, so they're here.

Every buff has effect cellTwo abilities from the same slot don't stack: the new one simply displaces the old one, even if it's weaker. This is why "overriding" a buff with someone else's buffer is a real problem, not a myth.

Here are all the slots that have more than one skill:

Own buffs. Skills that a character can equip only to themselves are a separate topic: there are about one hundred and fifty of them, and they are tied to specific classes.

Dance of Medusa. It's often included in dances, but it's not a buff: the skill hits enemies around it and inflicts paralysis.

Skills from scrolls and items. They duplicate some of the buffs from the tables, but with their own values.

The number of buff slots is determined by server settings, so citing a specific number here is pointless—it varies across different projects. What's important is: Songs and dances are counted separately from regular buffs, they have their own queue, and the overflow of one does not affect the other.

When there's no room left, the new effect displaces the oldest one. Therefore, the order of application matters: whatever was hung first will fall first.
