This doesn't throw any bombs. All it does is stack about two dozen TNT nodes about two blocks in front of you and hopes you can get the heck out of dodge before they start exploding.
I downloaded this hoping that this would add something like Rangedweapons adds with it's grenades: a bomb/shell you can catapult over fort walls and across fields to attack your opponents when they aren't expecting it. Hopefully there will be changes to this mod that make it a little less "wave a stick to place a heap of lit TNT" and more "fire a launcher to send an explosive projectile far away into my enemy's base."
The stick spawning tnt is made for easily expanding caves for easier mining, and the new dungeon master does throw bombs(tnt), and as for there not being throwable bombs, the name currently was for the tnt explosions sending other tnt into the air and getting thrown somewhere else, but I am sorry that this mod dissapointed you.
edit... I have just added one throwable bomb. It looks like a tnt stick just like the tnt spawner, but instead of spawning tnt it explodes. and I have added a smoke bomb
