Phase Venom Bracelet

The bracelet’s appendages wrap tightly around the wrist as the fangs inject an endless trickle of distilled phase spider venom. The venom empowers you with a modicum of the spider's power.
When an attacker that you can see hits you with an Attack, you can use your Reaction to attempt to phase through it. The attacker must roll the attack again with disadvantage
You have a climbing speed equal to your walking speed.
You can move up, down, and across vertical surfaces and upside down along ceilings, while leaving your hands free.
Overdose. As an action you can cause the venom to surge into your veins. You must make a DC 14 Constitution saving throw, taking 4d8 poison damage on a failed save, or half as much damage on a successful one. For the next one minute you can use your bonus action to magically shift from the Material Plane to the Ethereal Plane, or vice versa. Once you use this feature, you can’t use any of the brackets features again until the next dawn.

Requires attunement
