Hi, Lerix123!
Basicly fighting on TA seems to be quite easy...
I got my Mage just to Lvl 30 and the only Monsters I got by clicking the huge amount of them is just One Blue City Guard between Lvl 30 and Lvl 34. So the only thing you have to check is how much damage is done to you after your first hit...
In my case BCG Lvl 30-32 VERY EASY :-)
Lvl 33 hard
and Lvl 34 I always have to run away... :-(
You get credits for every monster you kill for which you can purchase goods in the supply tent, but I suppose this is more interesting for higher levels....Check Larkinorguide to get more info...Sandy and his supporters did a great job with it.
Hope this will help
good luck on TA...
