Sarachnis OSRS: Mid-Game Setup and DPS Check

A practical mid-game benchmark

Sarachnis sits in a useful gap between basic melee training targets and mechanically heavier bosses. Her 400 HP and 150 Defence make accuracy visible without demanding end-game equipment.

The calculator's time-to-kill is uninterrupted attack time. Add movement, web binds, healing, spawned spiders and looting to estimate a real trip. That difference is also why two players with similar listed DPS can report different kills per hour.

Upgrade rule of thumb

Prioritise an upgrade when it improves both crush accuracy and strength at a reasonable price. If an item adds only a fraction of a max hit and leaves hit chance unchanged, supplies or survivability may buy more real kills per trip.

A complete Sarachnis attempt

Before entering, decide whether the goal is learning, a pet or a steady supply of loot. A learning setup can deliberately trade a little DPS for armour, prayer restoration and an emergency teleport. Once your trips end with supplies unused, compare a more aggressive weapon or a smaller food reserve in the calculator rather than copying a maximum gear list.

During the fight, keep the boss in a position where web movement and spawned spiders do not force repeated pathing. Web binds and the add phase create periods where your character is not attacking, so a weapon that is slightly slower on paper may be easier to keep on target. Record actual kill duration from entering combat to the final hit; that is the number that belongs in a trip estimate.

• Confirm the target is Sarachnis and use a crush attack style before comparing weapons.
• Keep enough prayer and food for a web or add sequence rather than planning around a perfect kill.
• Separate direct attack time from movement and recovery time in your notes.
• Use the cheaper setup until you can explain what the expensive upgrade changes in your own log.

Reading the calculator result

A 400 HP target with 150 Defence is large enough for accuracy to matter, but the displayed TTK still assumes every attack opportunity is available. Compare two setups by looking at hit chance first, then average damage and time-to-kill. If one setup has lower DPS but lets you finish a trip with more food, its real kills per hour can be higher because you bank less often.

As an example, 50 seconds of direct attack time plus 20 seconds of movement, web and loot overhead is a 70-second encounter. That is roughly 51 encounters per hour before banking. A five-second weapon improvement only matters if it does not also increase the number of banks or force a more expensive supply loadout.

When Sarachnis is the wrong benchmark

Sarachnis is useful for checking a mid-game crush setup, but it is not a universal predictor of performance at raids or high-defence bosses. Its defence profile, web behaviour and add pressure reward different choices than a target with high crush defence. Use the page to make a Sarachnis decision, then run a separate target comparison for the next activity you actually plan to do.

Turn a trip into a decision

After a few runs, calculate three numbers: average seconds per kill, average seconds per banked trip and average supplies consumed. These make upgrade decisions comparable. A weapon that saves four seconds per kill may be worthwhile if it also adds one kill per trip; a weapon that saves four seconds but still leaves the same bank frequency may not repay its cost quickly.

Use the source links for current boss mechanics and the calculator for a controlled comparison. The guide's value is the connection between those two pieces: it tells you which input to change, what the result leaves out and which observation from your own trip should update the estimate.
