Requirements:

Spout

Features:

Toggle between arrow types by left clicking or if you are using the SpoutCraft launcher you can use the , and . keys to cycle forward and backwards through arrow types. GUI for users using the SpoutCraft launcher.

Seven unique arrow types:

Normal: Just the standard arrow, uses one arrow per shot.
TNT: Explodes on contact, by default uses one arrow and one tnt per shot.
Lightning: Strikes area with lightning on contact, by default uses one arrow and one diamond per shot.
Fire: Lights hit area on fire, by default uses one arrow and one wool per shot. Now emits smoke when flying!
Iron: does four damage instead of two, by default uses one iron ingot and one arrow per shot.
Diamond A.K.A Razor: does six damage, by default uses one diamond and one arrow per shot. They are razor sharp!
Smoke: Releases a cloud of smoke upon hitting something, by default uses one gunpowder.

Permissions (These are super perms):

The use of permissions can be toggled on/off in the config file if off it will allow players to use allowed arrow types (specified in config) while ops can use all. If permissions are enabled the use of arrows is based on the following nodes, note these are the Bukkit-integrated super perms so you cannot use third party permission plugins like permissions: EffectiveArrow.use.explosive EffectiveArrow.use.lightning EffectiveArrow.use.flaming EffectiveArrow.use.iron EffectiveArrow.use.razor EffectiveArrow.use.smoke Or use EffectiveArrow.use.* to use all arrows! I highly recommend using bpermissions for managing super perms.

Notes:

The arrow effect works both on contact with entity and blocks; however with blocks there is a small delay. I would be more than happy to implement new features/arrow types if they are well balanced and the requests are well thought out and politely phrased.
