the tunic is fine, I can ensure you (and I'm the one who knows about
gilding).
But the whole clothing/gilding mechanic should be reviewed and heavily overhauled, because "let's put some random numbers and random affinities in both cloth and gilds" is too dumb/unfun/imbalance and removes a whole bunch of both gilds and clothes from use.
Sadly, devs aren't playing that hard to spend months on gildings so I doubt they can understand it, and thereby won't ever even look at it.
And if this topic will result in any changes with a tunic - it will be soooo bad for industry.
