What are the best spawns for pure experience for level 600+ duo mages to hunt together?

Question

As the question states whats the best spawn for duo mages (MS/ED)600 + to experience together and has places to run if enemys come?

Answer 1

The best one right now is Kilmaresh Steppe (Issavi surface), respawn full Young Goanna , Adult Goanna, Feral Sphinx  and Manticores mostly.

The second best place in my opinion would be the Brain Grounds (The souls access in Jakundaf Dessert from the Feaster of souls quest). The -1 and -2 floors are the best to hunt, they are full of Flimsty Lost Souls  , Mean Lost Souls and Grim reapers .
