This Soulforged Arcane Core is the culmination of years of research into occult runes and the arcane magics that animate golems and manipulate souls. You have created an enhanced arcane core powered by souls to fuel a construct.

The arcane core has 3 charges that recharge at dawn.

When creating a construct, you may have that creature automatically attune to this magic item.

Soul Overdrive. For a short period, you can stoke the souls encased in the arcane core to enhance your abilities. On your turn, you may expend one of the core's charges to enter a state of overdrive for 1 minute. While in overdrive, you gain the following benefits and drawbacks:

• Soul Burn: Pushing your arcane core past its limits comes at a price. At the end of each of your turns, you must make a Constitution saving throw (DC 10 + Frost). On a failed save, you take 2d6 cold damage. This damage can't be reduced or prevented in any way.  On a successful save, you increase your Frost by 1.

• Stabilize. As an action, you can stabilize your core. Your Frost is reset back to 0 and you don't need to make a saving throw for Soul Burn at the end of this turn.

• Danger Zone. Blue soul flames envelop your body. Your melee attacks deal an extra 1d6 cold damage. While you have 5 or more Frost, you deal an extra 1d6 cold damage (for a total of 2d6 cold damage).

• Overclock. As a bonus action, you can call upon your Soulforged Arcane Core to empower your and another construct's reaction time. You may increase your Frost by 2 to give you and another construct you can touch an additional reaction this round.

• Soul Speed. Once per turn, you can infuse a construct with heightened speed. You may increase your Frost by 1 to increase the movement speed of a construct you can touch by 10 feet this round.

You can end Soul Overdrive on your turn as a bonus action.

The core takes some time to cool down. You get 1 point of exhaustion each time you use this ability within an hour after the last use. Exhaustion gained this way carries over between constructs attuned to this item until it goes away naturally.

Enhancement. The Soulforged Arcane Core be further enchanted and upgraded over time, allowing you to unlock additional abilities.
