Galvanic Neck-Bolts

Wondrous item, very rare

These metal bolts, if held next to a creature’s neck while it suffers over 10 points of lightning damage, affix themselves permanently to the creature’s spinal column.

Removing the galvanic neck-bolts requires a DC 25 Wisdom (Medicine) check (inflicting 2d6 points of damage and 1d3 levels of exhaustion).

Once implanted, galvanic neck-bolts enable the target’s body to absorb lightning damage and convert it into raw strength, speed, and power. Galvanic neck-bolts can absorb and convert up to 60 points of lightning damage per day. Any lightning damage that would be suffered is ignored, converted into 1 temporary hit point per 3 points of electrical damage. These temporary hit points last for 1 hour or until lost.

In addition, for every 20 points of electrical damage absorbed you have advantage on Strength, Dexterity, or Constitution ability checks for 1 hour; if 40 or 60 points of electrical damage is absorbed, this bonus must be applied to different abilities. After absorbing 60 points of electrical damage, galvanic neck-bolts overload and shut down until the following day. The feedback from this overload inflicts 1d4 levels of exhaustion.
