White Phosphorus

For the more stable and common allotrope, see Red Phosphorus. White phosphorus (abbr. WP) is a very volatile and uncommon phosphorus allotrope. It comes as a waxy white bar, slightly yellow (why it is sometimes known as Yellow Phosphorus), that glows. Due to its volatility, it burns the player when held. It is highly toxic. Like most other dangerous materials, its block form is not dangerous to hold.

Obtention
It is only obtained by centrifuging Nether Phosphorus ore.

Uses
It is not as useful as Red Phosphorus, but it is still useful for tipping bullets as it burns extremely easily and well.

WP coated bullets give entities shot with it the "Phosphorus Burns" effect, which is like fire, but it cannot be put out by water and lasts for about a minute.

WP can be used in small explosives like rockets or grenades as WP spreads easily as smoke.

 * WP is nicknamed "Willie Pete" after the WWII Allied Phonetic alphabet for "WP".
 * WP is technically not banned as it has non-weapon applications (usually smoke shells and grenades).
