The Barrage Stone is a Sidearm Ability Tarstone you earn by clearing the combat trial near the Gloomshade Grove Beacon, and it lets a compatible sidearm spend 40 Resolve to fire a heavy round that scatters explosive projectiles below the target.
The Barrage Stone turns a sidearm into a small artillery piece: one shot lobs a heavy round that bursts in the air and rains explosive projectiles onto whatever is underneath. It is not lying in a chest — you have to earn it by beating a short gauntlet at a trial monument in Gloomshade Grove, and once it is yours you can bolt it onto the Forgotten Crossbow or another compatible sidearm and pour upgrade materials into it. Here is exactly where the trial sits, what the stone does at every level, and how to level it.

Barrage Stone effects and its four upgrade levels
| Level | Effect |
|---|---|
| Level 1 | Consumes 40 Resolve to launch a heavy round that detonates above the target, scattering explosive projectiles below. |
| Level 2 | The heavy round detonates 2 times, with each explosive projectile dealing around 8 splash damage. |
| Level 3 | The heavy round detonates 2 times, with each explosive projectile dealing around 8 splash damage. |
| Level 4 | The heavy round detonates 3 times, at the highest tier, with each explosive projectile dealing around 8 splash damage. |
Key At its base level the Barrage Stone reads exactly as it does on the in-game screen: Consumes 40 Resolve to launch a heavy round that detonates above the target, scattering explosive projectiles below. The payoff comes from stacking levels — higher tiers make that heavy round detonate multiple times and push more splash damage into each projectile, which is why it pairs so well with a rapid-firing sidearm.
The number of detonations and the level pattern are consistent, but the exact per-projectile splash damage is approximate — different community measurements land on slightly different figures, so treat the damage values below as ballpark rather than frame-perfect.
Upgrading the Barrage Stone and the sidearms it fits
The Barrage Stone only attaches to a Sidearm, so slot it onto something like the Forgotten Crossbow and the heavy-round skill replaces that weapon’s normal ability. To take it past Level 1 you need to unlock Tarstone upgrades: hand Franz the Etching Needle at Marrow Keep, and from then on you can level the stone up to four times as you gather the materials.
Bank a full 40 Resolve and equip the stone on a compatible sidearm before you walk into a fight — the heavy round is useless mid-combat if the meter is short.

Frequently Asked Questions
Which sidearms can the Barrage Stone be equipped on?
It works on compatible sidearms only. The Forgotten Crossbow and Naylshotte both take it, and it also slots onto pistol-type sidearms, making it a natural fit for explosive-projectile builds. Anything outside that compatible set will not accept the ability.
How much Resolve does the Barrage Stone cost to fire?
Each heavy round costs 40 Resolve, the meter you build up during combat. Because that is a large chunk, you generally want to charge it before you commit — trigger it with less than 40 banked and nothing fires.
Is the Barrage Stone the same as the beta’s Tarblighted Trophy Tarstone?
Yes. The powerful Tarblighted Trophy Tarstone from the beta was renamed for the retail build and is now the Barrage Stone, one of several Tarstones that changed names or locations between the beta and launch.
