Tactics

When combat begins, the Matriarch will attempt to hatch her nearby Phase Spiderling eggs. These eggs can be destroyed before the battle begins if the party can stay hidden. Failing that, area damage spells work well on their low Hit Points.
The Phase Spider Matriarch will use its phase abilities to teleport around the arena.
At 50% or less Hit Points, the Matriarch will cast Spider Queen's Wrath on itself, entering into an enraged state.
Knocking the Phase Spider Matriarch into one the side holes labelled 'Chasm' will grant the party 250xp. However, knocking her into the centre hole (not labelled 'Chasm') will not grant experience, but its corpse can be found in the Underdark (X:140 Y:151) to loot and possibly animate. This does not work in Honour mode.
Using Alchemist's Fire (or other fire spells) when the Matriarch is on a web bridge, will destroy the web bridge and causes 45 fall damage and can help defeat her.
Use Elixir of Poison Resistance on all your party members before entering combat
Lump the Enlightened and his ogres can prove valuable allies in the battle. They can be recruited just up above in the Blighted Village through a Charisma check or paying them 500g. This can result in a win-win situation where Lump is killed in the battle or is significantly weakened allowing the opportunity to easily obtain the Warped Headband of Intellect.
She has +1 bonuses to Strength and Dexterity on Tactician difficulty, with resultant bonuses to Initiative, Armour Class, Attack rolls, and Saving throws, making an already fairly fierce early game enemy even deadlier.
It's a good idea to spread party members out. Her venomous discharge ability has a large AoE radius.

History
