About this Mod

Sea Weapons

"When tridents arent enough"

This Mod Currently adds two weapons, The "Anchor Hammer" and The "Nautilus Longsword"!

3 Skins of the Anchor Hammer!

Use (Anchor Hammer):

  • When you right click on a block with this weapon, you create a shockwave effect
    that pushes entity's away from the block, including you, wich allows you to do bigger jumps!
  • The Anchor Hammers also return to the correct slot after throwing it like you throw tridents!
    (thanks to HollowedWanderer)

Use (Nautilus Longsword):

  • When you hold right click you will see an icon appear (while in first person), this indicates the charge, when its full you can shoot out a wave effect when you let go! this is canceled by sneaking.
  • While charging/using the longsword, it works as a shield that blocks 2/3rds of incomming damage but can be dissabled by axes!
    (wich also stops you from charging the attack, so watch out!)

Use (Ancient Vine):

  • When right click it will shoot out an ancient vine projectile that will pull you into it when it has collided with a block, allowing it to work like a grappling hook!.
  • You can only have one projectile at a time but you can reel it in again by right clicking when it is out!

Enchantments:

  • SWING: This removes the ability to throw the anchor hammer and instead makes it do a continuous area of effect attack wich makes you swing around with its chain, dealing damage to enemies around you!
  • FORCEFUL: This simply makes the shockwave effect fro the anchor hammer push entities further!
  • SHOCKWAVE: This makes the wave effect from the longsword go in all directions while looking straight down!
  • SPOUT: This make the Nautilus Longsword spout water in a concentrated beam, damaging entities that are in the way and pushing you away from them!

Skins:

(purely cosmetic, gotten from sneak right-clicking a smithing table)

  • Royal
  • Coral
  • Ebonite
  • Ruby
  • Abyssal (for the Nautilus Longsword)
  • Sculk (for the Ancient Vine)
  • Golden chain (for the Ancient Vine)
