Since wind and lightning had very little to no weight on their own, these properties were imbued into the Shimmering Sky Trail Titanite.
And as such, they were also added to the alloy when mixed in the right ratio.
But this wasn't the only reason why Lin Mu had picked it. Since it had the lightning element in it, it was of the extreme yang orientation and thus had a slight ability to resist a curse too. This, when mixed with the Immortal Green Gold and the Immortal Silver, resulted it in being in a nearly perfect harmony.
The two noble metals when mixed resulted in a very heavy shaft which Lin Mu didn't think would be the most ideal for an arrow, especially since it was only one half of the arrow and there were more parts that would add weight to it.
Thus he had to make adjustments wherever he could while also making it durable.
