Grand Court of Sebelkeh (Hard Mode)
I did the Grand Court of Sebelkeh mission in Hard Mode last night using the builds posted below. The rest of the party spots were filled with Cynn, Herta, Mhenlo and Khim. The Margonites never knew what hit them. :twisted: Of course, it helps that Menel's Lightbringer title is maxed out. Master's for this mission is less than 12 minutes (finished it in about 6). Riding on that success, I went on to do Nundu Bay as well. However, Margrid was switched out for Melonni (since she is required). Similarly, Jennur's Horde may be done using the same party configuration (but switching out Margrid for Koss).

Do the pets help that much in Hard Mode? I would think that, in many areas, the pet would be dead and the skills useless.

It's only one pet and it actually stays alive very well. The main point of taking a pet is so help keep casters interrupted. After BHA hits them and they're dazed, any attack they receive interrupts them. Sometimes I can't take an MM or have to focus on more than one target. Setting Margrid on one caster with her pet effectively shuts them down.
