I just accidentally got the Armed and Dangerous achievement, which is for giving +9 attack in one game with Arms Dealer. Somehow I hadn’t accomplished that one yet, but in this one game I managed to give +18 attack, so I guess that covered it. It actually gave so many buffs the achievement notice triggered multiple times.
In the same game I also got the one for using Titan abilities 160 times … and my crowning maneuver was stealing Sargeras from my opponent and using him to do nothing with a nether I didn’t have. Well played, me, well played.
