Nora Cost: 80
Hit Points: 53
Amazingly, Gunbattery was actually released at 85 nora. A -5 nora buff hardly helped him, though.
Recommended Builds: Bash/Tremor
There's really no space for a Gunbattery in a Tortun deck.
11 effective range is impressive, though, as is 18 damage in an AoE 2. Although the damage is delayed one round, you will usually be able to predict where enemy champs will move. Your opponent will have to change his plans or eat the damage. Also, it can easily dispatch relics from very far away.
The only problem with him is his cost. 80 nora for a support unit with very meager combat capabilities is extremely steep. While he's cool, and potentially useful, you'd be better off with pretty much any other Tortun.
