Description
This mod is my first proper project for Hytale. I don't have a lot of experience with modding in general, but I've figured out a lot of things while making this.
Major update (1.0.0)
I've added crafting. Now Murasama is available in survival too. It's very expensive due to the blade's power, but it's available.

Moveset
Attacks change depending on your movement inputs (mace behaviour)
Standing still
3-part combo, containing left and right swings and a stab
These attacks deal low damage but regenerate stamina
Forwards (W)
1. 2-part combo, containing left and right swings
They're the same as the ones you can use when standing still
2. Chargeable lunge
When charged for 0.75 seconds, lunge forward, dealing moderate damage and consuming 3 stamina
When charged for 1.5 seconds, jump into the air and then lunge forward, dealing high damage and consuming 5 stamina. Immune to fall damage
If you're out of stamina, perform a regular stab instead
Sideways (A/D)
Directional (again, depending on your movement) chargeable swings
These attacks deal moderate damage and have more reach than regular swings
When charged for 0.75 seconds, increase reach, deal high damage, and consume 1.5 stamina
If you're out of stamina, perform an uncharged directional swing instead
Backwards (S)
Vertical chargeable swings
These attacks deal moderate damage and have more reach than regular swings
When charged for 0.75 seconds, jump forward and hit enemies upon reaching the ground, dealing high damage and consuming 3 stamina. Immune to fall damage
When charged for 1.5 seconds, jump into the air, then dash forward and down, hitting enemies upon reaching the ground, dealing extreme damage, and consuming 5 stamina. Immune to fall damage
If you're out of stamina, perform an uncharged vertical swing instead
Signature - Blade Mode (Q)
Slows down time for enemies in a radius, allowing you to easily deal a lot of damage without being threatened
I didn't find a way to stop enemies from attacking, or to increase your attack speed. There are effects that are supposed to do this but when I tried to apply them they didn't work. Maybe they're not fully implemented into the game yet
Videos are from an older version. I'm planning to update them.
