The Last Colony (Patreon)

Weapon (rapier), rare (requires attunement)

An elegant blade with a hilt grown from living coral. You gain a +1 bonus to attack and damage rolls you make with this magic weapon.

Creeping Reef. As an action you can stab this weapon into the ground and cause a 40-foot radius bed of coral to spring into existence. Each other creature in the radius must make a DC 15 Strength saving throw. On a failed save the target becomes encrusted in coral. A creature encrusted in coral has its speed reduced to 0 until it or another creature uses an action to break away the coral.

The coral spreads 10 feet at the start of each of your turns until the sword is removed from the ground or the coral reaches its maximum radius of 100 feet. Any creature in the expanding radius at the start of your turn must make a DC 15 Strength saving throw, becoming encrusted in coral on a failure.

The coral is considered difficult terrain for all creatures other than yourself and remains for up to 10 minutes after the sword is removed from the ground, after which it all turns to dust. Once you use this property it can't be used again until the next dawn.

Ghost Shell. As an action you can touch an unconscious creature at 0 hit points with this weapon and stabilize the target by petrifying it. If the creature receives magical healing while petrified the petrification ends.

Hollow. Empty. Dying. The coral beds lay in disrepair from years of suffering from no fault of their own. Pale and gaunt, their vibrant colors now lost to the bleached skeletons that now cover the expanse beneath the waves. But it is not yet long past to bring this environment back to the thriving condition it found itself before. Spread the coral far past the reefs, entrench its presence upon the land and make sure it shall thrive and survive even after its source may fade into memory. Do not forget what was lost, and do not forgive those that stole it from us.
