As of right now, we can use our legend inks to get various small boosts for our characters. Or...
...We can get an enchant. Both of which we can have pumped out as much as we'd like from the tower.
Which says to me that one tower run is equivalent in difficulty of getting from 1-60. Or that these enchants are a very high price for something that's now trivial to obtain.
Could this shop get a makeover of some kind and have some items that are truly worth all the trouble of spending legend inks on?
