MyDifficulty

This plugin adds per-player difficulty settings that are chosen on joining of a server. The three difficulties are:
GREEN

• Take damage from mobs roughly equivalent to easy vanilla difficulty
• Only lose 10% of your items on death

YELLOW

• Take damage from mobs roughly equivalent to normal vanlla difficulty

RED

• Take normal hard difficulty damage

Setup:

• Install the plugin and set your server to hard difficulty "/difficulty hard".

Players with permissions can override the difficulty chosen by other players with /setdifficulty
