Wicked Reptilian Magic

One of my favorite creations over at the Hamsterish Hoard of Dungeons & Dragons is the reptilian Sshian.  These feathered snake-people make an awesome buried-and-forgotten ancient evil for the PCs to accidentally re-awaken.  Of course, when you're looting their tombs, you need to find suitably wicked magic items.  The following were written for 5e, but there's really nothing that needs doing to convert them over to the OSR game of your choice:

Claw of the Lictor
An ornate orichalcum gauntlet with three clawed fingers and little tubes for affixing feathers, the claws themselves are fashioned from black iron. The gauntlet is a simple finesse weapon enchanted to a +1 to hit and damage. It does 1d6 slashing damage. It’s also vampiric; any damage you do to a living creature that draws blood regains you hit points equal to the damage roll.

Looking into the gauntlet reveals a series of hooks, blades, and gears inside the Claw. In truth, it’s not meant to be a gauntlet, but rather a prosthetic replacement hand. Putting a living hand into the gauntlet will cause the gauntlet to eat the hand up, doing 2d6 damage and, assuming the wielder survives, grafting itself to the arm. Only a remove curse or wish spell will allow you to remove the gauntlet.

Crimson Thorn Scourge
This six-tailed scourge is fashioned from braided lengths of manta-ray-like hide, studded with thorn-like hooks of orichaclum. Treat it as a whip that has a +1 to-hit and damage enchantment on it, does 1d6 damage, and is vampiric, giving the wielder 1 hit point for each point of damage caused. The target must make a STR saving throw vs. the attack roll or be restrained (PHB pg 292) so long as it is size Large or smaller. Every round the target is restrained, the whip can’t be used as in an attack, but it automatically does 1d4+1 damage to the target. The target can escape if they roll a STR save of 12 or better.

If the wielder rolls a 1 on their attack, then the wielder is tangled in the web and becomes restrained, suffering 1d4+1 damage (which is not fed back to them via vampirism). The wielder can escape on a STR save of 12+.

Sanguine Cords
A trio of crimson ribbons, stitched minutely with black runes, are attached to a small gold ring. At the end of each ribbon is a small obsidian plumb weight. If a spell-caster of any sort makes a loop through the ring of the cords, places their dominant arm through the loop, and then wraps the chords along their arm, they can then sacrifice 2 HP to increase both their spell attack bonus and save DC by +2. When they do this, their dominant hand exudes a brief crimson mist that trails their gestures.

If the spell being cast causes piercing or slashing damage, the bonus is automatic and does not require the user to sacrifice any hit points. Prolonged use can lead to any garments being worn on the dominant hand or arm to be stained as if with a mist of blood.
