Would love to see Masamune in mod.
One handed katana with very long reach, could be balanced by giving it below-average damage and slow attack speed. Has multiple abilities that can be used depending on if item is in off-hand or main-hand, along with alt keys.

• Main-hand ability 1: Use to shoot out projectile similar to moonlight beam but in purple color

• Main-hand ability 2: Press alt to teleport behind and above the last hit entity within 10 blocks range, automatically attacking by impaling from above to deal high damage (more damage if against posture broken entity.)

• Off-hand ability: Use to cast elemental magics ranging from Fire, Blizzard, Aero, and Thunder, can be cycled by pressing alt.

• Fire/Fira/Firaga: Fires fireball that explodes on impact. Hold down to increase the tier to Fira then Firaga, higher tier has slower projectile speed but has bigger explosion and damage.

• Blizzard/Blizzara/Blizzaga: Fires ice projectile that creates ice crystal on impact then explode after a bit. Ice crystal inflicts slowness to entity nearby before exploding. Hold down to increase the tier to Blizzara then Blizzaga, higher tier has larger ice crystal and takes more time before exploding, it also has higher damage.

• Aero/Aerora/Aeroga: Creates wind vortex at where the cursor is, pulling in nearby entity before exploding. Hold down to increase the tier to Aerora then Aeroga, higher tier has larger vortex and stronger pull but has delay before appearing (appears as small harmless particles during the delay).

• Thunder/Thundara/Thundaga: Cause lightning strike at where the cursor is, creating small and instant explosion with below average damage. Hold down to increase the tier to Thundara, then Thundaga, higher tier has higher damage and slightly larger explosion, but has delay before lightning strike (appears as small harmless particles with light during the delay).

Cool idea, I'll consider it for the next big update.
