The Sound of Drums

One of the nice things about being a leatherworker are the rather nifty raid consumables that you can produce in the shape of drums. There are four recipes which can all be bought from vendors either at the right rep or from the leatherworker trainer.

Drums of Battle - Simply the best drum there is, haste rating and spell haste rating for your group for a whopping 30secs. I use this on Crash whenever heavy burst damage is required or on fights like Aran where threat isn't an issue. Pick this recipe up from the Sha'tar once you've ground your way to honored.
Drums of Panic - Pretend you're a warlock/spriest and have your enemies running around in fear. Ideal for battlegrounds if you need a few seconds with people off your back or just getting that warlock in trouble in a raid. Available at honored rep with Keepers of Time and a great recipe for getting those last skill points up to 375.
Drums of Restoration - A group wide potion effect for mana and health which doesn't share a cooldown with any of the other goodies such as potions or health stones. Available at honoured reputation from your faction representative in Nagrand.
Drums of Speed - Sprint in musical form, again this is a nice PvP buff esp if you've been brave enough to venture into WSG. Again you can pick this up from your faction rep in Nagrand once you're honored.
Drums of War - The first recipe you'll pick up from the leatherworker trainer and provides a nice AP buff which stacks with any other buff you can get your hands on. Crash uses this in preference to the haste rating on the Prince fight, when melee haste on our tank might cause an extra parry or two which can lead to a bit of a mess.

A brief outline but hopefully enough to encourage everyone that can to make and carry these whilst instancing/raiding or running a battle ground.
