While outside the fortress, press the O key to enter tactical view. You will be able to fly to the rooftops. Just watch out for some stun traps on the floor.
I leaned heavily on the Illithid abilities so I have flight available on my MC at all times. I'll need to buy or craft potions of Flying for the others.
I tried several times to break through Wyrm's Rock's heavily trapped hallways and I just can't handle it lmao. Too many grenade launchers, and flame throwers. If it was just Fist of Bane guys, it wouldn't be a problem, but the grenades one shot me.
