The title says it all.

Cooldown for MetalClips

Made a few changes, but ultimately not working.
Modified the three-clip control.

With three clips on the enemy, the metalbender has sharper control over
the enemy's movements. It works just like it does with 2 clips
(identical code) except the movements are faster. This makes it
different from BloodBending.
Added a "MagnetPower" Config Option for MetalClips

The strength at which metal objects will be pulled towards you when you
sneak.
Changed the loot item...

Changed the item which allows looting players' inventories of all iron
items to an Iron Ingot named "Magnet". The player still requires the
appropriate permission to use this variation of MetalClips.
