Hamstring

# How it works

«Hamstring» is a single-target physical skill with range 600. Cast 1.5 seconds, cooldown 2 seconds, lasts 60 seconds. Lowers the target's «Speed» by 30%, the same on all 14 levels: only the skill level and MP cost grow with level.

# What it does not stack with and why

Debuffs are divided into groups. Within one group only one effect works on a target, while effects from different groups work together and their reductions are multiplied.

Every effect in a group has a strength. It is set for the skill and is not the size of the reduction. When another effect of the same group is cast on a target that already has an effect of that group:

1. The new one's strength is higher or the same - the new one replaces the old one.
2. The new one's strength is lower - the new one does not land, the old one stays.
3. It is the same skill with the same strength - the new use does not land, the old one's time is not refreshed.

In the second and third cases the success message still comes, and the MP and the cooldown are spent.

The strength of «Hamstring» in its group is 3.

# What it stacks with

«Block Wind Walk» and «Mass Block Wind Walk» also lower «Speed», by 10%, but this reduction is part of the block itself and is not in the «Hamstring» group. So both effects work together in any order of application, and neither replaces the other.

Target's «Speed»

What is on the target	Multiplier	Summary
Only «Hamstring»	× 0.7	-30%
Only «Block Wind Walk» or «Mass Block Wind Walk»	× 0.9	-10%
«Hamstring» and the block together	× 0.7 × 0.9 = 0.63	-37%

# Chance and enchant

The skill's base chance is 80%. It depends on the target's «MEN», the level difference and the target's debuff resistance.

Two enchant routes: chance - the base chance grows to 100% at +30; time - duration from 62 seconds at +1 to 120 seconds at +30.

Tested on a test bench with the server's effect stacking rules and skill data.

What stays on the target

Order of use	On the target	«Speed»
«Hamstring», then «Frost Bolt»	«Hamstring»	× 0.7
«Frost Bolt», then «Hamstring»	«Hamstring»	× 0.7
«Hamstring» and «Block Wind Walk», in any order	both	× 0.63
The same, «Block Wind Walk» removed	«Hamstring»	× 0.7

# Specifics of our server

Using «Hamstring» again on top of an active one does not refresh the time: to extend the effect you have to wait until it ends. Before the change of 10.10.2026 «Block Wind Walk» and «Mass Block Wind Walk» pushed out «Hamstring» and did not let it be cast again; now they work together.
