You propose destroying the box the same
At this time, visit the bank and stock up for a struggle. Head to Oldak and tell him you’re ready. Sigmund and Johanus Ulsbrecht will teleport in, alongside the HAM mage and HAM ranger, and OSRS gold some guards. Sigmund utilizes his 43 prayer, again, and Johanus can use range and melee, in addition to prayer.
After 1 minute of fighting, several Lumbridge Guardsmen, led by Jimmy that the Chisel and Aggie (remember One Little Favour?) Will appear to arrest the HAM members, so you will just need to worry about Sigmund and Johanus then. Zanik will require Sigmund, while Johanus comes in you. You can either use an Ancient Mace (it won’t eliminate his salvation though), full Veracs, or you might just switch fashions every now and then.
When they are all dead, the HAM members will operate. No, they are not dead after all. Oh well. Zanik picks up where she left off. You point out that the box at Yubiusk slammed shut after you freed her. Zanik says that since it has a few energy of Dalgroth, it’s near indestructable. Zanik cites that while trapped, she learned stuff about Bandos, including that Dalgroth is his supernatural ability, making some of his ogre followers near immortal.
You propose destroying the box the same way you conquered the Ogre Shamans in Watchtower: using a potion. Head to Yanille and make a potion just like the one from Watchtower, in other words, with guam foliage, jangerberries and bat bones. Though I do not know what order you create it because it DOES matter. When you have made the potion, take it to cheap RS gold the Watchtower Wizard and ask him to enchant it. Head to Dorgeshkan and lender to get a Massive battle. Inform Oldak you are prepared, and he will lead you to his portal machine. The box will burst.
