These are the new arrows that will be added in 1.9, they are in order:

• Spectral Arrow, makes anything you hit have an outline. (if you hit a mob, you will be able to see it from behind a wall, the outline color changes based on the team the entity / player is in, ex.: Red team = Red outline, Blue team = Blue outline, etc.)

• Poison Arrow

• Slowness Arrow

• Fire Resistance Arrow

• Water Breathing Arrow

• Weakness Arrow

• Levitation? There are no purple potions in the game at the moment...

• Invisibility Arrow

• Strength Arrow

• Healing Arrow

• Regeneration Arrow

Note: I edited the design to make it appear as my latest design.
