General Info:

Sarachnis is weak to crush attacks and has high magic and ranged defense. Weapons aside from the Scythe of Vitur should be used with the crush combat style option, if there is one available. Sarachnis will attack with melee when within melee distance from her and with ranged when outside of her melee distance. Players should pray melee when within melee distance and pray ranged when outside melee distance to mitigate damage, as Sarachnis is very accurate. Your quick prayers should be set to Protect from Melee and Piety. However, upon first entering the room, you should turn on Protect from Missiles until you are within melee distance of Sarachnis.

Mechanics:

Healing Strike

If you are hit off-prayer by Sarachnis she will heal 5 hitpoints for a successful melee attack or 10 hitpoints for a successful ranged attack, regardless of how much damage she deals to the player(s).

Sticky Web

After every 4 standard attacks Sarachnis will "Hsss" and shoot a sticky web at the player(s) in the room, trapping them for around 3 seconds.

Spawns

When Sarachnis reaches 66% and 33% hitpoints she will spawn 2 Spawns of Sarachnis per player in the boss room. 1 level 68 spider that uses magic attacks and 1 level 107 that uses melee attacks. Both spawns have 30 hitpoints but it is not advised to kill them as they will die as Sarachnis is defeated and don't deal a significant amount of damage.
