Feature description
Adding features to two existing tool types in tetra, the hammer and the shortblade from Xercamod's warhammer and knife.

Hammer would get some niche combat use as a knock-back heavy weapon, which hits must be charged similarly to trident to deal maximum damage / knock-back.
Also featuring enchantments:
Heavyweight: Increases the maximum pull time, but also adds more damage and knock-back.
Legerity: The opposite of Heavyweight, lets you pull the hammer faster while having the same power. These two enchantments cannot be applied on the same item.
Maim: Cripples your opponent on hit, applying a Slow effect on them. Especially useful when your knocked back opponent is trying to run away!
Uppercut: Adds a “knock up” component to the hammer. A way to use fall damage to your advantage or an unorthodox method of vertical transportation.
Quake: Allows you to target the ground. When you hit the ground, all enemies around the target point are damaged according to their proximity and knocked back from that point.

Short blade receiving additional use in combat, allowing off-hand usage and providing additional damage when attacking while sneaking and facing back of the enemy. Also additional enchantment and possible blade - improvement:
Silent Killer: Increases the bonus damage applied on sneak back stabs.
Venomous: Applies poison effect to the target on hit. Be careful, as the poison effect is not lethal - originally being an enchantment, might be a module to apply to any blade type.
The changes would apply while having xercamod installed and this would disable original items

How it improves the player experience
It would improve some aspects of tools usually used mainly for crafting purposes, opening new play styles with the back stab mechanic.

Tetra synergies
It fits current weapons, further expanding their usage.

I won't add this to tetra, but perhaps it is something they could add on their side.
