Dr. Cyano's Wonderful Wands add a magical flair to your Minecraft game without breaking it. The wands are balanced around mid to late game, requiring lots of emeralds and gold. The most powerful wand, the Wand of Death, requires Wither Skulls to craft, making it a serious investment for a dedicated mob slayer.
This mod also adds Wizard Robes and the Wizard's (and Witch's) Hat. The Wizard Robes can be dyed any color and they combine the enchantability of gold armor with the durability of iron armor (but provide less defense than leather armor). The Witch's/Wizard's hat can absorb potion effects, making them permanent so long as you wear the hat (can be disabled in the config files).
