I can't seem to find anything using the offline tool.

This would be for single player. It's so annoying having them die from the stupidest stuff, I just want a companion who will stick around providing buffs, some additional damage, and a distraction.

What's WDM?

Ohms are recommended in certain places but wouldn't a Perfect Ruby work in armor and save the Ohms for non-armor pieces?

I'm in Hell in the Throne of Destruction and I just beat all of Baal's minions. Can I not enter his chamber to kill him and beat the game on Hell?

Is there a way to remove mystic orbs from an item and keep the original item (to redo the MOs)?

Should you still get your mercs from normal or has the bug been fixed?

Or guides in general on how to gear them with MOs and such for those of us that want to put in the time and effort?
