Actions

Multiattack: 2 amalgamation sword attacks, or 1 Spike Toss attack

• Amalgamation sword: +9 to hit, 10ft reach. On a hit, 17(2d10+6) slashing and 9(2d8) bludgeoning. A creature struck by this attack must succeed a DC 17 Strength saving throw or be knocked prone.
• Spike Toss: The Sword Elemental whips it's tail-like limb and fires 3 small blades at a target it can see within 60ft(3 attack rolls). +9 to hit and on a hit, each blade deals 11(1d8+6) piercing and 3(1d6) poison damage. A creature that suffers this damage must succeed a DC 14 Constitution saving throw or become poisoned and lose 10ft of movement until the start of the Sword Elemental's next turn.

Reactions

Consume Weapon: The elemental's body is made up of countless blades, and it is always hungry to add more to the pile. When the Sword Elemental takes weapon damage, as a reaction, it can attempt to integrate the weapon into it's main body. The Sword Elemental rolls a strength check vs the opponent's acrobatics or athletics check(Their choice). If the Elemental wins the contest, the opponent is disarmed, and the Elemental gains any magical effects the weapon might have. Weapons consumed by the elemental are destroyed after 1 hour.   The weapons taken this way can only be retrieved after killing the Sword Elemental, but they now have an additional +1 to hit and damage on top of their previous abilities up to a maximum of +3. (Non-magical weapons become magical)
