 One torch bomb will fire up to 42 torches (though usually much less than that) in a radial pattern around itself, with a minimum range of 5 meters (the torches are going too fast closer than that and shatter without a trace) and a maximum range of 40 meters from the detonation point. Torch bombs are falling nodes when lit, much like TNT.
 
-TNT is an optional dependency, but torch bombs don't have a crafting recipe without this mod enabled.
+Three torch bombs can be combined into one mega torch bomb. A mega torch bomb can fire up to 162 torches with a range of 120 meters from the detonation point (three times that of a regular torch bomb). The minimum range of this monster is 15 meters, and it produces enough of a blast to destroy nodes within 3 meters, so take care. One of these is suitable for illuminating a very large cavern with walls and ceiling too distant to reach otherwise.

+TNT is an optional dependency, but torch bombs don't have a crafting recipe (and don't produce a damaging blast) without the tnt mod enabled.
