Voidwaker gem

“The gem of a broken sword.”

The Voidwaker gem is one of the three parts of the Voidwaker, not a weapon you can wield. It drops from Venenatis and Spindel, and you need it together with the hilt and the blade to have the weapon rebuilt. This page is about the gem alone: where it comes from and what it becomes. The finished sword has its own page at Voidwaker.

How to get the Voidwaker gem

The gem is a rare drop from two Wilderness bosses, and it can also be bought.

Ways to obtain it
Venenatis — 1/360. She lives in the Silk Chasm. To enter her lair you need the medium Wilderness Diary tasks done, or a Venenatis boss Slayer task.
Spindel — 1/912.
Grand Exchange — tradeable, buy limit 8 every 4 hours.

The gem is paired with a hilt (Callisto or Artio) and a blade (Vet'ion or Calvar'ion). Each part has the same 1/360 and 1/912 split, so a full set is three separate boss drops.

Turning the pieces into a Voidwaker

Bring the gem, the hilt and the blade to Madam Sikaro in the Ferox Enclave Dungeon. She charges 500,000 coins to put them together.

What you get is a melee sword needing 75 Attack, with a 4-tick swing, +70 stab, +80 slash and +80 strength. Its special attack, Disrupt, uses 50% special energy and always hits with Magic damage of 50% to 150% of your maximum melee hit.

Gem or finished Voidwaker?

Buy the gem if you already hold the hilt and blade, or if you are farming the other two pieces and want to finish the set. If you hold none of the three, the cleanest comparison is the sum of the three part prices plus the 500,000 coin fee against the finished sword's price.

Do not buy the gem on its own as an upgrade, because it does nothing until it is combined. If your goal is a good melee weapon rather than the Voidwaker itself, see melee gear.

Voidwaker gem FAQ

What is the Voidwaker gem used for?
It is one of three parts, with the Voidwaker hilt and Voidwaker blade, that Madam Sikaro in the Ferox Enclave Dungeon rebuilds into the Voidwaker for a fee of 500,000 coins. On its own it has no use.
Where does the Voidwaker gem drop?
From Venenatis at 1/360 and from Spindel at 1/912.
What are the other two Voidwaker pieces?
The hilt drops from Callisto (1/360) and Artio (1/912). The blade drops from Vet'ion (1/360) and Calvar'ion (1/912).
Can you combine the Voidwaker pieces yourself?
No. If you try, the game tells you that you do not think you have the skills to reassemble the weapon yourself. You have to take all three pieces to Madam Sikaro.
Is the Voidwaker gem tradeable?
Yes. It is tradeable on the Grand Exchange with a buy limit of 8 every 4 hours, so you can buy it rather than farm Venenatis.
Do you lose the Voidwaker gem if you die in the Wilderness?
You can still lose it. Since 2 February 2023 it no longer turns into coins when you die in the Wilderness, but it follows the normal death rules, so it can be lost if it is not one of your kept items.
What level do you need for the Voidwaker?
The finished weapon needs 75 Attack. The gem itself has no requirement, because it cannot be wielded.
Is it better to buy the pieces or the finished Voidwaker?
It depends on the live prices. Add the prices of the gem, hilt and blade and the 500,000 coin fee, then compare that total with the finished Voidwaker.
