This mod allows you to have wands that change blocks to the block associated to the wand. This mod is a work in progress though, if it isn't obvious enough, But I did make the Water Wand and Lava Wand.
All Wands: 10 Attack Damage, 1600 Durability, Special Abilities can be triggered by Right Clicking a block, Right Clicking the air, and/or Hitting an entity. Right Clicking a block special ability uses 5 durability points.
Lava Wand Special Ability: Right Click Block: Turns the block into lava, Alt Ability: Hitting an entity burns it for 6 seconds. Recipe:
Water Wand Special Ability: Right Click Block: Turns the block into water, Alt Ability: None. Recipe:
