Bukkit

NB: Spell descriptions leave out any special effects or particles in the spells. Not all of them look as boring as they sound! Also NB: The sacrifices listed are only the defaults! They might be different on your server.

food

fissure

voodoo

• Type: Short-range entity-targeting
• Sacrifice: 1 obsidian, 1 netherrack, 1 soulsand
• Effect: Forces the target to move as you do for 7.5 seconds. That is, if you cast it on a creeper 5 blocks north of you, it will move to stay 5 blocks north of you as long as the spell is in effect.

superjump/featherfall

• Type: Self-targeting
• Sacrifice: 1 ladder, 1 cloth
• Effect: If casted on the ground, launches you into the air. If casted in the air, causes you to take no falling damage when you hit the ground.

summonwolf

arrowshield

• Type: Self-targeting
• Sacrifice: 1 iron ore
• Effect: For 50 seconds, any arrows shot at you will fall out of the air once within a few blocks. The effect is large enough that you could theoretically shield somebody else if they stood right next to you.

grabitems

• Type: Block-targeting
• Sacrifice: 1 obsidian
• Effect: Any items within a few blocks of the block you look at will drop into your inventory. Maximum range of 100 blocks.

taunt

locator

• Type: Self-targeting
• Sacrifice: 1 iron ore, 1 redstone wire
• Effect: After casting, hold an item you get from mining an ore (besides lapis). You will be teleported into the same column as the closest-to-the-surface ore of that type near you. If you're above sea level, you will be teleported to the highest block in the column. If you're below sea level, you'll stay at the same height. If the destination is inside blocks, the 2 you are in will be removed to prevent suffocation.

fusrodah

• Type: Short-range entity-targeting
• Sacrifice: 1 bookshelf, 1 soulsand
• Effect: Sends the target flying in the direction you're looking when you cast it.

meteorite

• Type: Block-targeting (requires blaze rod)
• Sacrifice: 1 obsidian, 2 fire
• Effect: Causes a block of obsidian to fall from the sky above the block you target (up to 100 blocks away). On impact with a solid block, any blocks other than obsidian or bedrock within a 5-block radius will be obliterated, the base of the crater will be set on fire, and any entities other than Ender Crystals and Enderdragons within the area will be killed or destroyed.

barrage

• Type: Block-targeting (requires blaze rod)
• Sacrifice: 1 gravel, 1 log
• Effect: Shoots 20 arrows over the course of a second. Each arrow can kill a full-health Ghast from 30 blocks away. The arrows will disappear a bit later.
• Note: This is quite possibly the spell with the most possibility for abuse. It has the power of fissure (or more!) AND it gives you the mana for your kills because it uses arrows. If you run a server with this plugin, I strongly recommend that you put the mana cost somewhere above 200!

bunker

• Type: Self-targeting
• Sacrifice: 1 iron block
• Effect: Surrounds you in obsidian for about five seconds. I suggest that you stand still for a second while you cast it.

snowstorm

• Type: Block-targeting
• Sacrifice: 3 snow blocks
• Effect: Within a 5x5x5 cube: 1) Most things are covered with snow, 2) Water is frozen into ice, 3) Lava is frozen into cobblestone or obsidian, 4) Living entities (besides you) are trapped in ice.

heisalreadyhere

• Type: Short-range entity-targeting
• Sacrifice: 2 planks
• Effect: Allows you to be already here.

raise

• Type: Block-targeting (requires blaze rod)
• Sacrifice: 1 soul sand
• Effect: Resurrects up to ten mobs from their remains, which must be dropped on the ground near where you target the spell. Only one mob can be raised per item entity. Remains need to be remains; for example, you can raise a skeleton from a bone, but not from an arrow.
