Lvl 40-45 Grinding Location? (at Least For Archer)

So i was loafing around in the snow biome near the great bridge and went into the cave that leads to the tower of ascension and managed to get on top of a ledge using the escape spell for the archer class and realised that this was a good grinding spot. I found it when i was lvl 42 and i'm now almost 45

I think it works for mage too, not sure.
coords are:

X: -111
Y: 66
Z: -553
then croach so while you go to the side so Z turns to -552 and then use Bomb spell while aiming directly down
