In Act 5.2 you acquire skill points, life bonuses, and various items or boons.

• 01.The Khari Crossing inside the Skullmaw Stairway - Molten One's Gift: +5% to Maximum Life. You might need to find a seal in the Khari Crossing and click it to open access. Seems a bit buggy - might need to find both seals, then reset the instance, then find the door again
• 02.The Khari Crossing - Torbek (Mechant): sells several rare Caster Weapons at a discount
• 03.The Khari Crossing: Slay the Worm and Scorpion - Risu will grant you +2 Weapon Set Skill Points ⭐
• 04.Qimah - Choice of 7 Boons (can be changed by returning here)
• 05.Sel Khari Sanctuary: Choice of 2: Rare Ring/Amulet/Jewel - find the Baryas of Rageen and Yoon, place them on the pedestals and they will grant you a wish for Jewellery
• 06.Qimah Reservoir - Restore the Wells for a Currency item from each (seems to be Exalt/Alchemy?)
