Songblade is a magic, sentient longsword that grants a +2 bonus to attack and damage rolls made with it.
Sirens Song. The sword abhors isolation, and longs to charm the world with its beauty. When not attuned to any creature, the sword sings an enchanting melody inside the mind of anyone near to it, enticing them to pick it up, growing louder and louder the longer it is left alone. When a creature touches the Songblade, they must make a DC 10 Wisdom saving throw, if the creature fails their throw they become charmed by the sword, falling under its spell. If the creature succeeds on their saving throw, they may break contact with the sword, or choose to pick it up. When a creature holds the Songblade they must make another Wisdom saving throw every 6 seconds, which increases by 3 for each throw, up to a maximum of DC 25. If the creature succeeds on the final throw, the blade secedes to them, and they become attuned to it.
While attuned to a creature, the weapons still sometimes tries to control them. Every dusk roll 1d8, on a 1, the Songblade attempts to charm the creature it is attuned to. The wielder makes a DC 25 Wisdom saving throw, with advantage if they have been attuned to the weapon for more than 5 days.
When a creature is charmed by the Songblade they must roll an Wisdom (insight) check against the sword's Charisma (persuasion) or follow the whims of the blade, which often compels them to show their prowess in combat or the preforming arts, challenging any worthy creatures they may encounter. The Songblade has a +22 bonus to persuasion checks. Every 10 minutes the creature can make a DC 20 Wisdom saving throw to break free of the swords hold, with a success breaking the charm. If they are not attuned to the weapon, they also drop the weapon to the ground. The creature makes the same roll whenever the blade causes them to attack any creature friendly towards them, they make this roll with advantage.
Song Craft. While a creature is attuned to the sword and deals damage with it, it rings out a fragment of an ancient song into the minds of all nearby creatures. Creatures with an Intelligence score of 6 or lower within 10 feet of the blade at this time must make a DC 14 Wisdom saving throw or be charmed by the blade and its wielder until the end of their next turn.
A Thunderous Noise. The blade charges with thunderous energy when it deals damage, gaining 1 charge for every 5 slashing damage it deals on that attack. When the Songblade reaches 1 charge its power is to great to contain and it deals 1d4 Thunder damage on hit. This damage increases to 1d6 at 5 charges, 1d8 at 10 charges, 1d10 at 15 charges, and 1d12 at 20 charges. When the sword reaches one charge, and whenever the die size increases, the slashing damage required to gain a charge also increases by 1. Additionally, at 20 charges each attack a creature makes with this weapon also releases the effects of a 1st level Thunderwave originating from the sword, affecting everyone in range including the wielder, who is knocked prone if he fails the CON Save. The Constitution saving throw for this ability is a DC 15 for the wielder, and a DC 19 for all other creatures.
The charges last for 1 hour from when the sword last dealt damage, at which point the sword looses 1 charges every consecutive hour it goes without attacking. The wielder of the Songblade can also expend some of its charges to cast one of the sword's spells as an attack action.
Sentience. The Songblade is a sentient chaotic neutral weapon with an Intelligence of 13, a Wisdom of 15, and a Charisma of 30. It can sense the minds of creatures within 1000 feet of it.
The weapon communicates telepathically with wielder, and other creatures around it. It can understand all languages, but cannot speak any. It instead communicates by conveying emotion through its song, which it often uses to hypnotize or harm other creatures.
Personality. The sword is dangerously egotistical and overconfident. It is obsessed with its own beauty and grace, and considers itself to be the epitome of elegance. It desires to show the world its superiority though it often feels like it is held back by its wielder. When attuned to the sword, creatures become slowly fixated on honing their skills in the performance arts and graceful combat. The wielder gains the following flaw when attuned to the Songblade: "I turn everything into a competition, and cannot decline a challenge. I believe myself to be better than all others when it comes to things that matter."
