Is there any other way to go back and forth between Ishad N'Ha and Brimloch Roon except through the Dragonspire? I've finished the Dragonspire and gone back to Ishad N'Ha. Now I'm ready to move on, but I haven't found another way.

Well -
If you have high enough athletics you can climb the outside of the spire near where it meets the tress (over by Torin), otherwise you will have to trudge through the spire again.
Do you have Create Portal, Teleport and Call of Home yet?? If not, get them soon. If you need to come back to Ishad N'ha again you can at least make a portal for yourself on the other side of the Spire and save yourself a walk next time!

Thanks, Wyv. Jeeezzze, you musta been looking at me while I was typing that question. Talk about F-A-S-T!!! Ok, I didn't know about athletics. Mmmmnnn. Do all the characters have to have it, and how high? As for spells, I guess the ones you mentioned are fiend spells. Nope, don't have them yet. My warlocks are fairly new 'cause I started them late (around level 15 or so).

Well I am not Wyv, Uncle Joe, but I can tell you that someone mentioned an athletics skill for just one of their characters of 12 (or higher) that enabled them to climb the outside wall of Dragon Spire with that character selected to lead.
The spells are Moon Spells.

Yes athletics level 12 worked for me, if you go to the wall of dragon spire just by torin you can climb there. Move up next to the wall move forwards and hit the shift key then look upwards and move the curser from left to right a little bit and you should start to climb.....if this doesnt work then try to climb at an angle. You can also use this angle trick to climb down when your going back to Ishad N'ha, saves you falling and geting damage.
