Doorway Rapier (Patreon)

Weapon (rapier), rare (requires attunement)

The guard and pommel of this blade resemble elegant doorknobs. You gain a +2 bonus to attack and damage rolls made with this magic weapon. When you hit a creature with a melee attack using this rapier, you can immediately teleport to an unoccupied space on the other side of the creature. The space you teleport to must be within 5 feet of the target and must be on the target's opposite border or opposite corner from where you made the attack.

When in doubt about whether a space can be teleported to, trace an imaginary line between your current space and the new one. If the line passes through opposite borders of the target creature's space (including corners of those borders), then the new space can be teleported to.

Knock. Knock.

A tiny slot opened in the door to reveal a monstrous, yellow eye. The voice belonging to the blinking orb answered "Not secret password. Go away!" And the shutter slid closed.

Knock. Knock. Knock.

Again, the tiny door opened, and the gravely voice abruptly answered "No!"—slamming the shutter this time.

Knock.

Now the guttural grunts could be heard even before the tiny door opened. "Stupi-frach'n chuppa retcha..." The door slid open again. "No. Wrong pass—"

Poke.

The tip of the blade tapped the little creature on the bulbous nose, and in a blink, the password was no longer necessary.
