I'm curious - what is the buffed AC on your decoy right now? And what character is it? You've created so many... ;)

Bear in mind that goblins and orcs are comparatively weak, even in HoF. You will need to have your crowd control techniques down by the Shaengarne Bridge and the Horde Fortress, however.

My decoy is a Gnome Fighter4/Paladin3/Rogue3/Illusionist8 (currently, I will max out Illusionist, and maybe add 1 more level of Rogue for some skills I need!).

He's added to his DEX at every level-up, and has Expertise maxxed out also. His AC is currently in the high 50's, when buffed.
