Does riding Lloid cause it to deal more damage on impact

The point of hitting the bomb is so the bomb move faster and it does more damage to the structures before exploding. If you just hit the bomb of at about *25% it will only be able to damage the the two types of wood blocks. At around *30% percent you can start to damage the light grey stone blocks and *40% you can damage the dark grey stone blocks.

The higher the percent the better because the bomb will lose speed with every hit to the structural objects. It does not affect the bomb's explosion, just how the bomb moves.

*Rough estimates based on game play over the last few days.

Through my experiences with the game so far, once you acquire so many of the same item the game will start to drop better versions of that item and continue to give improved versions until the stat cap for the item is reached. After that, the game will start to drop a different item and start that process over again.

Or at least this is how it worked for me, I got many of the same item in a row.
