Quick Answer: Load, Then Fire, Then It Detonates
Explosive Shot does not fire when you first press it — the first press loads a detonator bolt into the crossbow. The next crossbow attack fires that bolt, which explodes on impact and immediately detonates any Grenades caught in the blast.
So the usable loop is: press Explosive Shot to load, attack to fire the bolt, let the explosion detonate nearby Grenades, then reload when the clip empties. Treat it as a two-step skill, not a one-button attack.
Key Stats and Acquisition
- Category
- Active Attack (Crossbow · Projectile · Fire · AoE · Detonator)
- Tagged attack, projectile, ammunition, aoe, fire and detonator.
- Weapon requirement
- Crossbow
- Requires a crossbow equipped; the load/fire cycle lives on the crossbow weapon set.
- Acquisition
- Uncut Skill Gem (tier 5+ skill)
- Engraved from an Uncut Skill Gem; available from campaign drops and the Gemcutting menu.
- Clip / load
- Loads 1 detonator bolt per use
- Each press loads one bolt; the following crossbow attack consumes it.
- Role
- Grenade detonator + Fire AoE clear
- Primary value is instant Grenade detonation and a fire explosion on the bolt impact.
Requirements and Setup
Explosive Shot needs a crossbow and the attribute requirements of the gem (Dexterity-led for crossbow skills). It is engraved from an Uncut Skill Gem rather than found pre-cut, so the earliest you can use it is when a high-enough tier Uncut Skill Gem drops.
Because it is a detonator, it is almost never run alone — it is slotted next to Grenade skills (Explosive Grenade, Frostbolt Grenade, Poisonburst Grenade, etc.) so that firing the bolt also clears the grenades you have pre-placed.
- Weapon
- Crossbow (required)
- No crossbow means the load/fire cycle cannot start.
- Companion skills
- At least one Grenade skill
- Detonator value only appears when Grenades are in blast range.
- Uncut gem tier
- Tier 5 skill gem
- Confirm the current client tier before publishing numbers.
Ammunition and Reload Cycle
Explosive Shot manages a small clip of detonator bolts. Pressing the skill loads a bolt if the crossbow is unloaded; the next crossbow attack fires it; when the clip is empty, pressing the skill triggers a reload instead of a load.
Reload speed is modified by your crossbow's reload modifiers and support gems. A slower reload is the most common 'it feels unresponsive' complaint, especially on crossbows with a reload-speed penalty.
- Clip behaviour
- One bolt per load
- Each press loads a single bolt; the clip is intentionally small.
- Reload modifier
- Crossbow-dependent
- Verify the current client reload modifier on the specific crossbow.
- UnloadedUse Explosive ShotLoads a detonator bolt into the crossbow (no projectile yet).
- LoadedUse any crossbow attackFires the detonator bolt; it explodes on impact.
- Empty clipUse Explosive Shot againTriggers reload; wait for it to finish before the next load.
- Grenades nearbyBolt explosion landsDetonates Grenades in radius, then you reload or re-load.
Grenade Detonation Rules
When the detonator bolt explodes, every Grenade whose body falls inside the explosion radius is detonated immediately, dealing its full Grenade hit at once instead of on its normal fuse timer.
Detonation only reaches Grenades actually inside the radius. A Grenade sitting just outside the blast will keep its normal timer, which is the usual reason 'my Grenades did not go off'. Pre-placing Grenades tightly around the target and aiming the bolt at their centre is what makes the combo feel instant.
All valid Grenade types in range detonate together, so you can stack Explosive + Frostbolt + status Grenades and pop them in one bolt. The explosion itself is a fire AoE, independent of the Grenade effects it triggers.
- Detonation trigger
- Bolt explosion radius
- Only Grenades inside the radius are consumed.
- Multiple grenades
- All in radius detonate at once
- Stack types for a combined hit; out-of-range ones keep their timer.
- Order
- Place Grenades first, then load + fire
- If you fire before Grenades exist, you only get the bolt explosion.
Mechanics: Projectile, Explosion and AoE
The fired bolt is a normal crossbow projectile until it connects, so it benefits from projectile supports (Greater Multiple Projectiles, Chain, Pierce) for the travel portion. On impact it creates a fire explosion centred on the hit.
The explosion is the AoE body. Its size scales with the skill's area modifiers and support gems, and the detonated Grenades add their own AoE on top. This is why Explosive Shot reads as a clear tool: one bolt turns into bolt-explosion plus every Grenade you pre-set.
Because the detonator bolt consumes the clip, the skill's single-target profile is weak unless a Grenade was placed on the target. Use it for packs and for bursting a pre-marked rare, not for spammed single-target.
- Bolt travel = projectile (supports apply to the shot).
- Impact = fire explosion (the AoE body).
- In-range Grenades detonate simultaneously for layered AoE.
- Single-target is weak without a placed Grenade.
Load / Fire / Reload State Table
| State | Player input | Game behaviour | Next step |
|---|---|---|---|
| Unloaded | Use Explosive Shot | Loads a detonator bolt into the crossbow | Attack to fire the bolt |
| Loaded | Crossbow attack | Fires bolt; explodes on impact | Watch for Grenade detonation |
| Empty clip | Use Explosive Shot | Reloads the clip | Wait for reload to finish |
| Grenades nearby | Bolt explosion lands | Detonates Grenades in radius | Reload or re-load and repeat |
Support Compatibility
Supports split into clear-builders and boss-ruiners. Anything that multiplies projectiles or area helps the bolt explosion and the Grenade spread; anything that adds cast/reload cost or splits damage can hurt a skill that already has a small clip.
- Greater Multiple Projectiles
- Core (clear)
- More bolts = more explosions and more Grenade detonation points per press.
- Fire Infusion / Added Fire
- Core
- Scales the explosion damage directly; core for fire builds.
- Area / Magnified Area
- Core
- Enlarges both the bolt explosion and the Grenade blast overlap.
- Martial Tempo / Attack Speed
- Situational
- Speeds the fire cadence but does not fix reload time.
- Slowing / high-cost supports
- Avoid (boss)
- Extra cast or reload cost makes the two-step loop feel worse on bosses.
Support Loadouts by Stage
- LevelingFire Infusion + Martial Tempo + 1 area supportCheap, fast Grenade pops while campaign gear is weak.
- MappingGreater Multiple Projectiles + Fire Infusion + Magnified AreaScreen-wide Grenade detonation for smooth clears.
- BossingDrop multi-proj, keep Fire Infusion + Concentrated AreaTighter, harder hit on the pre-placed Grenade under the boss.
Weapon Set Splitting
Crossbow builds that use Explosive Shot usually run two weapon sets: one crossbow set that holds Explosive Shot plus Grenades (the burst set), and a second set that may hold a different crossbow or a utility skill.
The load/fire cycle is bound to the crossbow set that carries Explosive Shot. If you swap to the other set and back, the loaded bolt state follows the skill, but your Grenades must be on the same set you intend to detonate from. Players who report 'Grenades did not detonate' are usually firing from a set that does not carry the Grenades.
- Set 1 (Crossbow)
- Explosive Shot + Grenades
- The detonator combo lives here.
- Set 2
- Utility / alternate crossbow
- Keep Grenades on Set 1 unless you also move Explosive Shot.
Mapping Rotation
- Approach packThrow Grenades into the pack centreGrenades sit waiting on their timers.

Where It Is Used
Explosive Witchhunter uses Explosive Shot as the Grenade-detonation keystone: place Explosive / status Grenades, then pop them with the bolt for burst windows. Grenade Gemling and Tactician variants lean on the same detonator loop for AoE.
Some Deadeye crossbow builds borrow Explosive Shot purely as a fire-clear button when a Grenade skill is already slotted. In every case the skill's value is the instant Grenade pop, not the bolt damage alone.
- Explosive Witchhunter: primary detonator of the Grenade combo.
- Grenade Gemling / Tactician: AoE burst via simultaneous Grenade pop.
- Deadeye crossbow: occasional fire-clear button.
Troubleshooting
- Skill will not fireFirst press only loads; you must attack to firePress Explosive Shot once, then use a crossbow attack to release the bolt.
- Grenades not detonatingThey are outside the bolt explosion radius or on another weapon setCluster Grenades on the target and aim the bolt at their centre from the set that carries them.
- Reload feels slowCrossbow has a reload-speed penalty or a slowing supportSwap to a faster-reloading crossbow or drop the costly support for mapping.
- Mana problemsBoth Grenades and Explosive Shot share the mana poolAdd mana regen / Clarity or reduce Grenade uptime between detonations.
Community Evidence
Recurring community questions cluster on three points: 'Explosive Shot will not fire', 'my Grenades did not detonate', and 'reload is too slow'. Client testing confirms the first press loads (not fires), so the fix is to attack after loading.
The Grenade complaint is almost always a radius or weapon-set issue, not a bug: Grenades outside the bolt blast, or thrown on a set that does not carry Explosive Shot, keep their normal timer. Weapon Set splitting is the most reported setup trap for new crossbow players.
