OSRS Sarachnis Guide: Strategy & Gear Setup

Sarachnis is a level 318, spider-like monster found in a burial tomb in Forthos Dungeon. She is a great boss for players new to PVM and is also quite profitable. It can teach you basic PVM skills like prayer-switching and proper movements. She can be killed when assigned to a spider slayer task. Most players kill this boss because of its pet, which drops at a rate of 1/3,000, and the Sarachnel cudgel, which drops at a rate of 1/384.

How to get to Sarachnis

Players can find the Forthos Dungeon’s burial tomb in the southernmost part of the dungeon. They can enter the dungeon through the entrance inside and east of Forthos Ruin. Bring a slash weapon or knife to cut through the webs blocking Sarachnis' location. 

Players can right-click and peek through the webs to see how many players are inside the tomb. Another web blocks the tomb; it is thicker but does not require a slash weapon or knife to cut.

Here are the fastest ways to reach Forthos Dungeon:

• Xeric’s talisman: players can use the Xeric’s glade to teleport just east of the eastern entrance of the dungeon. This is the best option.
• Kharedst’s memoirs/Book of the Dead: the teleport option, “Lunch by the lancalliums” available on both items, teleports players by the River Hos just north-east of the dungeon entrance.
• Watson teleport: this teleports the player to Watson’s house, west of the Forthos Ruin
• Spirit tree patch: teleports the player south of the Ruin
• Lovakengj Minecart Network: taking the Hosidius West station of the minecart will take the player just south of the ruin
• Skills necklace: using the woodcutting guild teleports player south. Run north to get to the ruin
• Hosidius POH: the POH in Hosidius is not far from the Dungeon. Players can use teleport to house spells or tablets, then run to the dungeon if they have their POH in Hosidius.

Strategy for Killing Sarachnis

Sarachnis has high magic and ranged defence and is weak to crush, so ensure to use a good melee gear setup similar to the one above. Understanding Sarachnis’ attacks and how to avoid them is crucial when fighting her, as she is very accurate.

Sarachnis Attacks

Sarachnis has several attacks

• Melee attack: Sarachnis’s melee attack consists of smashing the player with her legs, which can hit the player up to 31 damage
• Ranged attack: She launches barbed projectiles, which can also deal up to 31 damage. She will only use this attack when the player is not in melee range.
• Healing strike: Sarachnis can heal for every successful standard hit, indicated by a magenta hitsplat. She heals 5 health for every successful melee attack and 10 health for every successful ranged attack, even if they hit zeros.
• Sticky web: After every four standard attacks, Sarachnis shoots out a sticky web, which will restrict the player's movement for 6 ticks (3.6 seconds). Before this attack, she will screech out “Hssss!”. After the attack, she will move a short distance away from where she was before attacking the player and attack with a ranged
• To avoid damage during this attack, pray ranged when she screeches. After she performs the attack, pray against melee and immediately continue to attack her before she performs a second ranged attack. Wearing the Aranea boots completely nullifies this attack. 
• Spawns of Sarachnis

When Sarachnis reaches 66% and 33% health, she summons two spawns of Sarachnis per player. These are blue and orange spiders. The blue one attacks with magic and the orange one attacks with melee. They have 30 hitpoints and have a maximum hit of 11. 

High-level players can ignore these spawns and continue to attack Sarachnis since they won’t be able to do significant damage to them. However, players with lower combat stats should first kill the spawn that attacks with magic (blue one) and then kill or ignore the one that attacks with melee (orange).

The best strategy to kill Sarachnis is to always stay in her melee range while attacking with melee, except when she performs the sticky web attack. Marking the tiles as shown below will help you to do this better. 

Additionally, only eat when you are trapped by her web to do more damage and save costs. When you have killed her, you should stand in the center before she respawns so she does not attack you with ranged

GP per hour from Killing Sarachnis

With the suggested stats, players can kill Sarachnis 30 times each hour. This rate differs depending on the player’s combat stats, speed, and luck.

Each kill is worth 31,500 GP. If the player can do 30 trips per hour, this will result in approximately 945,000 GP per hour. After deducting the costs of divine super combat potions, prayer potions, and food, the resulting profit is 537,654 GP per hour.
