I remember, way, way back when, the first time I beat the game was by abusing that on like level 2. I got to like level 5 or so on Formers and Imps.
...
This was back in like version .9.5 or so, tho. It was ... about 2005 or 2006.
Anyway. Actual question! What weapons *can* be modded by a technician? The wiki says all uniques... but I can't mod a Grammaton Cleric Beretta. What gives?
