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 neckbolts 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 t h a t 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.
