Reptile Slayer
Reptile Slayer
The Reptile Slayer is a Super Slayer item-property tag that grants a 2× damage multiplier against the broad reptile creature category — every dragon, drake, lizardman, snake, ophidian, and serpent in Britannia. As a Super Slayer, Reptile Slayer covers a wider range of monsters than any individual lesser-slayer (which targets a single creature type), making it one of the most popular all-purpose end-game slayer choices for melee, archery, and throwing builds. Its opposing slayer is Arachnid Slayer — a weapon tagged with one cannot be tagged with the other.
Reptile Slayer applies as a multiplier after the Damage Increase cap and after the Base Damage bonus stack — it is layered on top of the standard 300% damage cap, separate from it. Against a matching reptile target, a Reptile Slayer weapon's swing is doubled at the very end of the damage calculation, before Resistances.
Damage formula with Reptile Slayer
Damage = Base_Damage_Roll × (1 + AllMultipliers / 100) ← within 300% cap
× ReptileSlayer_2x ← if target is reptile
× Exceptional_1.30_to_1.35 ← if Exceptional tagged
× apply_Phys_split_resists(target)
Concretely, a Sampire on an Exceptional-marked Reptile Slayer Halberd against a Greater Dragon gets:
| Term | Multiplier |
|---|---|
| Base Damage Halberd | Roll(18, 26) — average 22 |
| Tactics + Anatomy + STR + Lumberjack + DI stack | up to +296.25% (capped at +300%) |
| Reptile Slayer (matching) | × 2.0 |
| Exceptional | × 1.35 |
| Phys split (default 100%) | × (1 − target.PhysResist / 100) |
The 2× from Reptile Slayer doubles every successful swing against any reptile-classified monster — the reason every PvM build that runs dragons, drakes, lizardmen, snakes, or ophidians keeps a Reptile Slayer in the rotation.
What counts as a "Reptile" target
The Reptile Slayer tag matches the following monster groups:
| Creature group | Notable members |
|---|---|
| Dragons | Dragons, Greater Dragons, Reptalons, Wyverns, Frost Dragons, Skeletal Dragons, Drakes |
| Lizards | Lizardmen, Lizardman Mages, Reptiles |
| Snakes | Giant Serpents, Coral Snakes, Lava Serpents |
| Ophidians | All Ophidians — Avenger, Knight, Mage, Matriarch, Shaman, Apprentice |
| Sleeping Dragon | Bosses with reptile classification |
| Hydras and similar | Multi-headed reptilian bosses |
| Sea creatures | Some sea serpents, leviathan-class reptiles |
The classification is engine-internal — the player cannot generally see which monsters are tagged "Reptile" except by experimenting with a Reptile Slayer weapon (the canonical "is this Reptile?" test is just to swing at it).
Reptile Slayer vs. specific lesser slayers
For some Reptile-class monsters, a more specific lesser slayer also exists:
| Specific lesser slayer | Targets | Reptile Slayer covers same? |
|---|---|---|
| Dragon Slayer | Dragons + Greater Dragons | Yes (Reptile Slayer = 2× same) |
| Snake Slayer | Snakes + Lava Serpents | Yes |
| Lizardman Slayer | Lizardmen | Yes |
| Ophidian Slayer | All Ophidians | Yes |
Each lesser slayer also delivers 2× damage against its specific group. So Reptile Slayer (Super) and Dragon Slayer (Lesser) deliver the same 2× damage against a Greater Dragon — but the Super covers many more monster types. This is the canonical reason Super Slayers are preferred for general-purpose builds; Lesser Slayers are kept for specialised single-monster grinds.
Sources of Reptile Slayer weapons
| Source | Mechanism |
|---|---|
| Random loot drop | Any monster can drop a Reptile-Slayer-tagged weapon |
| Champion Spawn drops | Higher-tier champ rooms drop slayer-tagged weapons |
| Imbuing | Reptile Slayer is an imbuable property — 1 intensity slot |
| Runic crafting | Higher runic-tier rolls can produce Reptile Slayer-tagged items |
| Reforging | Runic ingot rolls can land Reptile Slayer |
| Heritage Slayer instruments | A specific slayer instrument can be crafted with Reptile Slayer for bardic builds |
Reptile Slayer instrument (bardic build)
The Reptile Slayer Instrument is a parallel item — an instrument that grants the bardic skill check against reptile targets a 2× effectiveness in the Provocation, Discordance, or Peacemaking check. The mechanic mirrors weapon-side Reptile Slayer:
| Effect | On bard skill check |
|---|---|
| Effective Skill bonus | +20% against matching reptile (this is the canonical slayer instrument bonus) |
| Range | Standard bard range — 8 + (skill / 15) tiles |
| Stack with player skill | Additive bonus — pushes ineffective bard skill into effective range |
A 120 Music + 120 Provocation Bard with a Reptile Slayer instrument can reliably Provoke creatures up to 117 Barding Difficulty — pushing the Provoke target into the canonical end-game range (Yamandons, Dragons).
Imbuing Reptile Slayer
| Property | Max imbued intensity | Resources |
|---|---|---|
| Reptile Slayer (weapon or instrument) | 100% (Slayer is binary — present or absent) | 5 Enchanted Essence + 10 Magic Residue + 1 Slayer-specific gem |
The Imbuing menu offers Reptile Slayer as a single intensity choice — there is no "weak Reptile Slayer" intermediate tier; it's either present (full 2× effect) or not. The intensity cost is 1 of the 5 imbue slots.
Build implications
| Build | Reptile Slayer strategy |
|---|---|
| Sampire | Reptile Slayer Halberd is the canonical "every dungeon" weapon |
| Pure Mage | N/A — slayer doesn't apply to spell damage |
| Throwing Gargoyle | Reptile Slayer Soul Glaive for ranged dragon-killing |
| Tamer | Pet ignores slayer; Bard side may use Reptile Slayer instrument |
| Bard | Reptile Slayer instrument essential for bardic dragon/wyvern grinds |
| Archer | Reptile Slayer Bow + Reptile-tagged arrows for range matching |
Spawn-locked Slayer Quivers
Quivers can also carry a Reptile Slayer property — when equipped alongside a matching slayer bow, the quiver's slayer-tag adds a percentage damage modifier layered on top of the weapon's 2× slayer (a small but additive bonus). This is the canonical reason quivers are not just utilitarian — a Reptile Slayer Quiver on an Archer paired with a Reptile Slayer Bow stacks the two for a small net damage uplift against reptile targets.
