Hamstring is an independent effect and does '''NOT''' automatically occur on Disarm attempts
Hamstring can be used via the client's "Stun" hotkey, or toggled by using [Hamstring
Handling for Hamstring can also be configured in the Paperdoll -> Help -> Commands -> Mechanics tab
Use [HamstringUntoggleMode in order to decide how the automatic toggle works

Similar to Disarm attempts, if Hamstring is toggled for a player, on a missed attack they will not be able to make another Hamstring attempt for 15 seconds
Disarm and Hamstring are independent effects and can both be placed onto the same target at the same time (and have both independent cooldowns)
On a successful hit when Hamstring is toggled, a player will have a cooldown of 30-53 seconds (100-25 dex) before they may make another Hamstring attempt to any target
Once hamstrung, a player or creature cannot be affected by another hamstring effect for another 30 seconds

When a creature is hit by a Hamstring effect, they will be Entangled for 6 seconds (cannot move, but may still do melee attacks, spells, and abilities)
Hamstring effects applied to players from creatures has a 2 second duration

When a player is hit by a Hamstring effect, they will be reduced to 0 Stamina for 3 seconds (forcing them to walk), after which their stamina will return to its previous amount
When an attacker applies Hamstring during an Organized PvP Activity, and has 80 or more Raw Dexterity they have a chance to inflict a Battle Hamstring
