I used a level 29 Psyco against level 12 Baron with all the Mayors equipment I had over 500 instinct and Baron had Holy Scars on, I used Shock Therapy 3/3 with the electrical piercing passive thingy at 5/5 and dealt over 73000 damage!
use the pet sc button on the key board and then paste it in paint, then image host it and put the url here, so simple, wait i forgot how to host images, i think image shack or somthing.
