Version 0.31: This article may not be up to date for the latest stable release of Crawl.
This article is about stabbing attacks. For the removed potion, see potion of stabbing.
Stabbing can occur any time you deliver a melee attack to an enemy that is distracted, asleep, or otherwise unable to defend itself properly. These attacks deal significantly more damage, ignoring EV and SH. For a dedicated character, stabs can end combat in a single blow.
Contents
Stab Tiers
There are two types of conditions where you can stab:
High-tier stab conditions
Low-tier stab conditions
- Petrifying
- Held in a throwing net or web
- Blind (or if the player is invisible and unseen)
- Fleeing
- Charmed or otherwise friendly
- Confused
- Awake, but hasn't noticed you yet
- Distracted by damage from a non-player source or through Gozag's gold aura
Stabbing Odds
Your chance to stab depends on the tier of the stab:
- High-tier stabs are guaranteed, so long as your character is capable of stabbing.
- Low-tier stabs have a
1 + dex + (Stealth + Wpn_skill)/2% chance to stab.
50% of stabbing attempts with the Spriggan's Knife are treated as if the target is sleeping.
You cannot make stab attacks when:
- You are confused
- You have zero dexterity
- The target is invisible, and you cannot see invisible
- You are worshipping The Shining One (who considers stabbing dishonorable)
- You are attacking with Manifold Assault or Vhi's Electric Charge
- You are rampaging in seven-league boots towards a sleeping target (petrified or paralysed targets can be stabbed).
Monsters cannot stab. There are a few stab-like effects: a sleeping creature will take bonus damage from monster melee attacks, and a shadow deals bonus damage if it's invisible (and the target can't see invisible). However, these are completely separate from the stabbing mechanic.
Stabbing Damage
The additional damage from a stab attempt varies based on the target's status effect, the weapon you make the attack with, your skill with the weapon, and your Stealth skill. The stab tier and your weapon are the largest factors.
Short Blades are especially effective at stabbing foes. Felid claws, or any melee attack when wearing the hood of the Assassin, are considered equivalent to Short Blades for purposes of stabbing damage. All other stabs are identical.
Formula
There are three sources of damage, listed in order of operation:[1]
- Short Blades (and equivalent) get an innate source of flat damage. Daggers get an additional boost.
- All weapons get a multiplier to damage, which depends on stab tier, skill, and is increased when using Short Blades. This multiplier does not account for enemy AC, but does account for slaying, Fighting, brand, etc.
- All weapons get a flat bonus to damage on top. This is modified by stab tier only.
1. "Good Stab" bonus
- If using Short Blades or equivalent, take base value
DEX/10 × (1 + (weapon + stealth)/2). This is doubled for daggers. - If base value > 10 (after the dagger bonus), it is modified by
10 * log2(1 + base/10), where the final value is capped at 30. - Then, this value is multiplied by
1 + (weapon_skill + stealth)/20if high-tier, or1 + (weapon_skill + stealth)/80if low-tier. This number is added to your damage.
There is a breakpoint at base value = 35 for daggers, base value = 70 for other Short Blades, where the base value is maximised. The value multiplier still increases by skill, but the increase is smaller.
2. Multiplier
The stab bonus is a multiplier of damage before AC is applied. The table below details the damage multiplier from your skills, tier, and weapon type:
| Stealth/Weapon skill average | Short Blades | Others | ||
|---|---|---|---|---|
| High-Tier | Low-Tier | High-Tier | Low-Tier | |
| 1 | +19.2% | +4.6% | +8.3% | +2.1% |
| 2 | +40.0% | +9.4% | +16.7% | +4.2% |
| 3 | +62.5% | +14.2% | +25.0% | +6.2% |
| 4 | +86.7% | +19.2% | +33.3% | +8.3% |
| 5 | +112.5% | +24.2% | +41.7% | +10.4% |
| 6 | +140.0% | +29.4% | +50.0% | +12.5% |
| 7 | +169.2% | +34.6% | +58.3% | +14.6% |
| 8 | +200.0% | +40.0% | +66.7% | +16.7% |
| 9 | +232.5% | +45.5% | +75.0% | +18.8% |
| 10 | +266.7% | +51.0% | +83.3% | +20.8% |
| 11 | +302.5% | +56.7% | +91.7% | +22.9% |
| 12 | +340.0% | +62.5% | +100.0% | +25.0% |
| 13 | +379.2% | +68.4% | +108.3% | +27.1% |
| 14 | +420.0% | +74.4% | +116.7% | +29.2% |
| 15 | +462.5% | +80.5% | +125.0% | +31.2% |
| 16 | +506.7% | +86.7% | +133.3% | +33.3% |
| 17 | +552.5% | +93.0% | +141.7% | +35.4% |
| 18 | +600.0% | +99.4% | +150.0% | +37.5% |
| 19 | +649.2% | +105.9% | +158.3% | +39.6% |
| 20 | +700.0% | +112.5% | +166.7% | +41.7% |
| 21 | +752.5% | +119.2% | +175.0% | +43.8% |
| 22 | +806.7% | +126.0% | +183.3% | +45.8% |
| 23 | +862.5% | +133.0% | +191.7% | +47.9% |
| 24 | +920.0% | +140.0% | +200.0% | +50.0% |
| 25 | +979.2% | +147.1% | +208.3% | +52.1% |
| 26 | +1040.0% | +154.4% | +216.7% | +54.2% |
| 27 | +1102.5% | +161.7% | +225.0% | +56.2% |
3. Extra flat damage
All weapons get bonus damage equal to 1d<(weapon_skill + stealth_skill)/2> for high-tier stabs, or 1d<(weapon_skill + stealth_skill)/8> for low-tier stabs.
Strategy
"Pure" Stealth is less viable than other offensive skills. The enemy always has a chance to wake up... and training only Stealth means you can't deal with anything that wakes up. Plus, enemies often spawn in packs, and if one enemy detects you, they all wake up.
Thus, many stabbers will rely on magic to incapacitate their enemies. Hexes spells (like Ensorcelled Hibernation, Confusing Touch) as well as spells in certain other schools (Mephitic Cloud, Petrify, etc.) will give you opportunities to stab. Certain gods, like Uskayaw, can work in a similar way. A wand of paralysis is a limited, but powerful way to disable enemies. Also, any means of having allies can let you get distraction stabs here and there.
Gallery
In tiles, monsters will indicate whether or not they can be stabbed as follows:
? means they can be low-tier stabbed
zzz means they can be high-tier stabbed
History
- Prior to 0.27, stabs would bypass some of your target's AC, depending on your Stealth and weapon skills. This was converted into a flat bonus to stabbing damage instead.
- Prior to 0.20, The Shining One would inflict penance for stabbing intelligent foes that were not demons or undead.
- In 0.19, four tiers of stabbing attacks were replaced by just two tiers. Stabs against distracted and petrified targets were buffed: +50% damage and +100% damage, respectively. Petrifying and net stabs got -50% to damage, and invisible stabs had their proc chance reduced.
- Prior to 0.16, Long Blades were slightly more effective at stabbing than most other weapons, and clubs and rods could stab for special effects.
- Prior to 0.13, Stabbing was a skill of its own, rather than being the average of your Stealth and weapon skills.
