Ashe's Arrow Conundrum
So reading back over The Eye in the Abyss, a thought hit me. It's stated that nobody knows how to make True Ice anymore, and all the True Ice weapons in the world are now relics passed down from ancient times. We already knew this to be true of Serylda's Flail and Avarosa's bow, but I realized a small problem...
If nobody, not even the Iceborn Descendants actually know how to create True Ice weapons anymore, how does Ashe replenish her arrow supply, given that they also seem to be made from True Ice? Does she have to retrieve them after every battle? Do they just return to her quiver somehow? If not, then she has to use these arrows EXTREMELY sparingly.
Thoughts/ideas?
