Hello,
I won't get too in depth with this unless asked otherwise.
However, comparing the required materials for Sigrun Wings compared to other gear pieces similar to it, it has a much more difficult and less balanced process of acquiring piece compared to other gear pieces like it.
Specifically, the one material I find concerning, is the 10x Rose Quartz.
Compared to other mats for other gear similar in strength, Materials either need a lot of something easy to farm, some Midrange, a few hard range, or one to three much harder things to farm.
Item Example, Oni horns requires 3 horns of Tendrillion. Tendrillion spawns once an hour, drops Horn of Tendrillion at 90%+ chance. Only three.
Sigrun requires 10x Rose Quartz. Rose Quartz drops from Zherlthsh. Zherlthsh Spawns once an hour as well. However on top of needing 10.... It only has a 30% ish drop rate. This makes farming this material much more difficult especially when having to contest with other players. This material alone has (if lucky) A minimum chance of getting all the materials needed after ten hours (very unlikely) compared to the Oni Horns which would only take 3(Very likely) hours for its miniboss material
I suggest considering changing the amount of rose quartz needed personally, but changing the drop rate of the rose quarts or even changing the material needed to make it more balanced and obtainable would be very appreciated.
