Etherium Broadsword
A big blade for a big boy... Oh, wait, you're a girl?
It can be created in a Crafting Table, via shaped recipe:
Pressing Right-Click while holding Etherium Broadsword in mainhand will throw it's user back a few blocks. This ability could be used again after 2 seconds cooldown expires.
Etherium Broadsword has 3000 points of durability, similar to other tools made of Etherium. It is considered one of the three etherium tools that are usable as weapons, being somewhere in between the Etherium Waraxe and Etherium Scythe in terms of attack damage and speed. It's attack cooldown is sligthly longer than that of a regular sword.
It's active ability is designed to serve mostly in battles, allowing for quick retreat from opponents that completely rely on melee combat. High enough attack damage allows effective series of hits and retreats for charging next attack.
The only significant downside of Etherium Broadsword is that it doesn't serve as any tool, making it less multipurpose than Etherium Scythe or Etherium Waraxe. But it is still a good choice for balanced and dynamic combat.
