What a pickaxe can do

• Area oriented to the face you hit (wall, floor or ceiling), centred on the block, with optional depth. Sneak to break a single block.
• Effects while held (haste, speed, night vision…). Removed when you switch item, and never override a stronger effect you already have.
• Auto-smelt (with your server's furnace recipes), auto-pickup (drops and XP), XP multiplier and drop multiplier.
• Particles on every broken block and a sound on every swing.
• Rewards with a % chance per block (commands and message).
• Permission per pickaxe: without it, it works like a normal pickaxe.
• Enchantments, unbreakable, glint and custom-model-data for a resource pack.

Lore is generated automatically (lore.yml) and pickaxes already given update themselves when picos.yml or lore.yml change, keeping their durability.
