Thundering Bomb’s Bonus Damage Bug: What’s Happening in Throne and Liberty

This guide breaks down a current high-impact PvP issue in Throne and Liberty: dagger builds leveraging Thundercloud stacks to massively amplify bonus damage through Thundering Bomb. The result is burst so extreme it can delete even tanky targets if they’re missing key mitigation layers.

What you’ll learn: how the interaction is triggered, why the math becomes abnormal, what builds are most likely to run it, and the most practical counters you can apply right now while waiting for a fix.

Quick Summary (Non-Technical)

• Dagger users can apply Thundercloud stacks quickly, then detonate with Thundering Bomb.
• The extra hit from Thundering Bomb appears to be multiplying bonus damage per Thundercloud stack (instead of applying it once).
• Because bonus damage is largely unmitigated by many common defensive stats, the burst can feel like a true one-shot.
• The most consistent counterplay is stacking damage reduction and preventing/cleansing or resisting the Thundercloud stack application window.

The Core Interaction: Thundercloud Stacks + Thundering Bomb

The combo hinges on two pieces working together:

• Inject Venom with a specialization that applies Lightning Infusion, enabling you to build Thundercloud stacks on the target.
• Brutal Incision with the Thundering Bomb specialization, which triggers an additional hit that scales with the number of Thundercloud stacks.

What Thundering Bomb is supposed to do

In normal design terms, Thundering Bomb’s additional hit scales up as Thundercloud stacks increase. The ability description implies a multiplier that grows with stacks, which is already strong when you’ve fully stacked the debuff.

What it appears to be doing instead (the bug)

Based on in-game testing and damage formula checks described in the source, the abnormal behavior is that bonus damage is being applied per Thundercloud stack on the additional hit. In other words, instead of adding bonus damage once, it looks like the game is effectively adding it many times over when stacks are high.

At maximum stacks (commonly discussed as 20), the additional hit can behave as if it’s receiving something like 21 applications of bonus damage (the base instance plus the stack scaling), which is far beyond intended output.

Why This Deletes Players: Bonus Damage Ignores Most PvP Defenses

The reason this interaction is so oppressive in PvP isn’t just the size of the number. It’s what kind of damage is being inflated.

As described in the source testing, bonus damage is unusually effective because many common defensive layers do not reduce it in the same way they reduce skill damage. That means stats and effects players typically rely on can feel useless against this burst window.

Defensive stats that often don’t help much versus inflated bonus damage

• Defense and endurance (typical “tankiness” stats)
• Skill damage resistance
• Critical damage resistance
• Heavy damage resistance

The consistent mitigation mentioned is damage reduction. If you’re getting erased by this combo, it’s often because you’re caught without enough DR active or you’re not built to maintain DR uptime during skirmishes.

How Dagger Builds Trigger the One-Shot Window

Most versions of the setup follow the same rhythm: stack Thundercloud quickly, then land Thundering Bomb during a guaranteed-burst moment.

Typical setup sequence

• Apply Thundercloud stacks via Inject Venom with Lightning Infusion specialization.
• Enter stealth (or otherwise create a high-crit window) to increase the chance your detonation hits at peak value.
• Use Brutal Incision (Thundering Bomb) to trigger the stacked additional hit.

Why crossbow pairings spike even harder

While the interaction can show up on multiple dagger pairings, crossbow synergy is highlighted because it can add another damage amplifier through Detonation Mark, described as increasing damage by up to roughly 80% in the showcased setup. If Thundering Bomb’s bonus damage is already being multiplied per stack, adding another multiplier on top pushes the burst into “delete through reaction time” territory.

Offhand hits make it more volatile

Another reason the damage looks inconsistent (and sometimes even more outrageous) is that the detonation can trigger additional instances via offhand attacks. When the bugged additional hit can occur twice in a single cast window, the target can take two massive chunks before they can respond.

What the Testing Shows (Simplified)

The source describes controlled comparisons that match what many players are seeing in live PvP:

• With a moderate bonus damage value, basic attacks and non-stacked Thundering Bomb hits look normal.
• Once Thundercloud stacks are applied, the additional hit jumps far beyond expected values.
• When bonus damage is removed entirely, the stacked damage returns to expected numbers, suggesting the stack scaling itself is fine and the problem is specifically how bonus damage is being applied.

Why this matters for balance discussions

This kind of evidence is important because it points to a formula interaction, not simply “daggers are strong.” If the additional hit is incorrectly applying bonus damage per stack, then even modest gear can feel like endgame burst, and min-maxed setups become absurd.

Although crossbow/dagger is the most talked-about pairing due to Detonation Mark synergy, the source notes the issue is not limited to a single class identity. Any setup that can:

• rapidly apply Thundercloud stacks, and
• reliably land Thundering Bomb at high stacks

can threaten one-shots in PvP.

What to look for in enemy behavior

• They aggressively fish for a short setup window rather than extended trades.
• You see repeated attempts to build stacks, then a sudden commit.
• They try to hit you when your defensive buffs are down or you’re isolated.

How to Counter It Right Now (Practical PvP Advice)

Until it’s patched, you’re playing around a burst window that can be largely unmitigated unless you prepare for it. Here are the most reliable adjustments.

1) Prioritize damage reduction uptime

If you have access to DR sources (buffs, passives, gear lines, consumables, party support), treat them as “must be up” when you’re entering melee range of dagger users. The source specifically notes DR as the meaningful counter because it can reduce bonus damage where other stats may not.

2) Build and maintain weaken resistance

The burst requires stacks. If you can resist or reduce the application of the Thundercloud-related debuff effects, you can prevent the dagger player from reaching the lethal threshold quickly. Even partial resistance can force them into longer exposure windows where they’re easier to peel or punish.

3) Don’t give free setup time

Most deaths happen when the target allows the stack-building phase uncontested. If you identify a dagger player committing to you, respond early:

• kite and break line-of-engage where possible
• force them to spend mobility defensively
• use crowd control proactively before stacks reach critical mass

4) Treat stealth as the “detonation warning”

Stealth is often used to secure a critical detonation window. If you see a dagger user disappear after tagging you, assume the bomb is coming soon and shift to survival: refresh DR, create distance, and avoid standing still.

This bug is most punishing when you’re alone and can’t be peeled. In small-scale fights, play closer to allies who can interrupt, stun, or force the dagger user off you during the stack-to-bomb transition.

Should You Use This Interaction?

From a community perspective, players should treat this as a likely bugged interaction rather than “normal meta.” If you choose to play dagger in PvP right now, understand that outcomes may change quickly with a hotfix or balance update.

Also note that in competitive environments, relying on a bugged damage interaction can create unstable expectations for your build and your progression budget. If you’re investing heavily into bonus-damage scaling, be prepared for the possibility that the value of those investments shifts after a patch.

Progression Note: Why Bonus Damage Gear Is Suddenly Expensive

When a bug (or overtuned interaction) becomes widely known, the market tends to react. Items, traits, and upgrade paths that increase bonus damage often spike in demand. This is where Lucent for gear upgrades becomes a practical planning tool: whether you farm or supplement your budget, having flexibility helps you avoid overpaying during short-lived meta surges.

If you’re considering premium currency options, prioritize long-term value purchases (core upgrades you’d keep even after a fix) rather than chasing a single interaction. Some players with limited time look into Throne and Liberty Lucent options to stabilize their upgrade path when prices fluctuate, but it’s still smartest to invest in broadly useful stats and sets.

What to Expect From a Fix

If developers address this properly, the most likely outcomes are:

• Bonus damage is applied once to the additional hit (not per stack).
• The additional hit scales correctly with stacks, but without multiplying bonus damage repeatedly.
• Edge cases like offhand double-procs are normalized or reduced in frequency.

After a fix, dagger will still be dangerous, but the “ignore most defenses and erase tanks” behavior should drop dramatically.

Frequently Asked Questions

Is this only a crossbow/dagger problem?

No. Crossbow synergy can amplify the burst (notably with Detonation Mark), but any dagger pairing that can stack Thundercloud quickly and land Thundering Bomb can benefit.

Why am I dying through tank stats like defense and endurance?

The issue is that the inflated portion is largely bonus damage, which can bypass many typical mitigation stats. Damage reduction is the most consistent counter mentioned in testing.

Refresh DR before you’re fully stacked, avoid being isolated, and react to stealth as a detonation warning. If you can disrupt the stack-building phase, the kill threat drops sharply.

Should I invest in bonus damage gear right now?

Only if it fits your long-term build goals. If you’re using a premium currency budget, avoid chasing short-lived spikes; consider upgrades you’d keep even after a fix. Some players who buy Lucent do so to smooth out gearing without endless grinding, but the safest approach is investing in universally strong stats.

Will this be patched soon?

There’s no guaranteed timeline, but high-visibility PvP bugs often get prioritized. Plan as if it could change quickly, especially if your build relies on the interaction.
