A detailed guide of actual XEN values shown in percentile, with other synergies and combos explained.
For everyone wondering what on earth “slightly increases damage” means, look no further.
WIP. I am still working my way to acquiring all XEN, feel free to let me know what XEN I have to look out for and I will add them to the list.
What does “moderately increases damage” even mean?
This guide is WIP, and based on thorough testing in the shooting range comparing single XEN at a time for concrete % values, and then testing some in combinations with others or multiples of the same copy for further details. I will test all values myself before adding to the guide but please let me know about any synergies you have found or other XEN I should look out for to add to the list. Dedicated to all those who have often wondered; “what the hell does slightly, significantly, or moderately even mean?”.
…The short answer is, they mean nothing and there is little to no correlation between what the devs wrote in the English descriptions and what the modules truly do, so I decided it was worth finding out myself.
If you want to quickly look for some damage boosts, skip to the following categories:
Damage Focused XEN
Complex XEN and SynergiesEnjoy!
Barrels
Barrel
Details
Scatter Barrel
Scatter barrel causes you to do 3* ~40% damage shots.
Double Tap Barrel
Double tap causes you to do 2* ~60% damage shots.
Heavy Barrel
Heavy barrel gives ~50% damage increase, but 50% firing rate decrease (1.5x cd)
Approx damage per Attack point
(Firing Range)
0.2313624679
TBD: Turbine Barrel
- “Approx damage per Attack point”: versus static firing range enemies, a flat amount of damage was added per attack point, shown above. This will vary against enemies with different defenses, but was worth mentioning.
Barrel Interactions with Morph XEN
Barrel + Morph XEN
Effect
Scatter Barrel + Pinpoint Strike
Scatter barrel lowers to x3*3, after reduced dmg is weaker. It is lowered further to x3*2 at close range. (Bug?)
Scatter Barrel + Gravity
Five hits (Pulls)(x3), then explosion.
More TBD.
- Essentially seems that scatter barrel decreases the duration of duration based morph on top of decreasing the damage, which can really hurt the effectiveness of some morph by doubling drawbacks.
- Need to test if similar is the case with Double Tap barrels.

Self explanatory but has interesting synergy with additional light strikes. Each light strike added will hit the initial target plus the additional two targets (2+1 hits added per light strike) and the standard damage increase for multiple light strikes applies to them as well. (+15% Multiplicative damage to all Light Strikes). Additionally, 50% increased firing cost.
Hitting an enemy applies [Light Strike] to 2 other nearby enemies.
Epic
Elemental Entangle
Same as with Entangled State, but doesn’t increase the cost as well as adding elemental build-up, making this a very strong ability.

Epic
Torment II
Functions as stated.
Hitting an enemy’s weakness triggers 4 [Piercing]. – Deals damage equal to 1% of the enemy’s Max HP.
Rare
Apex Predator I
Functions as stated.
Damaging enemies with more than 80% HP remaining applies [Piercing] 4 times.
Synergy
Piercing Synergy
Piercing effects trigger off every hit bullet, so it is very easy to maximize these for example with the scatter morph and scatter barrel, quickly reducing any enemy to very low HP. Can be great to chunk high health enemies down, but won’t be very effective after the first hit if using apex predator, but with torment is very powerful, provided the enemy has a weakness easy to hit. (Or at all, like beacons.)
Uncommon
Pinprick
15% dmg increase to Light Strikes. No noticable effect when used with torment. You get the same dmg increase from multiple Light Strike XEN, but no increased amount of hits, making this worthless unless you lack Light Strikes early on.
Increases the damage of [Light Strike] and [Piercing].
Uncommon
Unstable I
Variance in damage appears to be from -15% to +30-35%, with something like 10% chance of dealing exactly double damage (separate from a crit).
Damage and efficiency fluctuate randomly and slightly.
Light Strike 5-7 “*Hyp” for Hypothetical, using already determined math.
