This is a conversion of the Sword of Kas to Baldur's Gate 3. It tries to be as faithful as possible to its design, with some liberty.

Description:

Metal dark as the night.

Bloodstone gems ornate the guard, a maw of shredded wings, ready to bite.

An obsidian fang crowns the hilt, eager to pierce a heart.

Engraved veins scar the blade, palpitating menacingly — the beating heart of the vile sentience within.

Effects:

  • []+3 longsword

    []+5 initiative

    []+1 critical threshold (general)

    []+2d10 slasing damage against the undead (only with the sword)

    []Resistance to Necrotic damage

    []Pommel Strike deals +1d4 piercing damage when Non Lethal is toggled off (easter egg, doesn't display in game)

    []Finger of Death at 7th level (no spell slot cost)

    []Call Lightning at 7th level (no spell slot cost, no concentration, no followup)

    []Vampiric Touch at 6th level (no spell slot cost, no concentration, no followup) There is a 1/6 chance the spell can be cast again without going into its long rest cooldown.

    []Spirit of Kas: Upon attacking with the sword in your main hand, you can choose to turn its +3 bonus to Attack and Damage rolls into a bonus to Armour Class until your next turn.

    []Bloodbath: Upon unsheathing it, the sword demands blood. You have a 2~5 turns to kill a creature that can Bleed , else the sword might claim control of you.

 DC 20 charisma saving throw, 3d6 psychic damage on success, become possessed on failure.

This can be prevented by Protection From Evil and Good, or removed by Dispel Evil and Good: Break Enchantment.

  • []Vampiric Blade: The blade deals an irrestible 1d6 necrotic damage to creatures that can Bleed, and heals the wielder for 1d3 hit points. The lifesteal is twice as potent if the wielder is a Vampire.

 This feature considers Astarion a Vampire.

It also has native compatibility with Path of Undeath.

[*]Aura of Treachery: A foul presence alerts whoever you talk to with distrust, and worriness. You have -3 and Disadvantage to Persuasion and Deception, but 3 to Int
