Summer Sweep Up - Agility & Chambers of Xeric Changes

OSRS Grand Exchange market analysis · Aug 12, 2026 · 13 items affected

Market analysis

Summer Sweep Up changes Agility access and Chambers of Xeric loot weights. The 12 August update is live. Hallowed Sepulchre floors 4 and 5 now require 77 and 87 Agility, with boosts allowed; the update gives a Summer pie as an example for reaching Floor 4. The Floor 5 coffin also accepts boosted 84 Thieving or 92 Agility. Colossal Wyrm runs are longer, with rewards adjusted to keep hourly XP and termite rates roughly similar.

Chambers of Xeric unique odds have been reweighted in Normal and Challenge Mode. Scroll odds per unique award fall 19.5% and 26.1%, respectively, while the other listed rewards become more likely. At comparable raid activity, that implies supply pressure for those items, not certain price moves; demand and raid participation can offset it.

Impacted items

• Summer pie · rising. Boosting is newly allowed for Sepulchre floor entry, and the update specifically cites a bite of Summer pie to reach Floor 4. If players use this route, added consumption could support demand, but the net price effect is uncertain.
• Ancestral hat · falling. Its chance per unique award rises 53.3% in Normal and 64.3% in Challenge Mode. At comparable raid activity this adds supply pressure, though demand and participation could offset it.
• Ancestral robe bottom · falling. Its chance per unique award rises 53.3% in Normal and 64.3% in Challenge Mode. At comparable raid activity this adds supply pressure, though demand and participation could offset it.
