I never could determine value of items until I got into crafting. Once you know what a suit maker/imbuer can craft, you can get an idea of whats "good", whats "great", and whats "Godly".
This has cold damage/dragon slayer. These can be crafted. the other mods arent very specific or key for any build. Meaning any crafter can make a cold damage dragon slayer, but they can add mods very specific to a players build to make it awesome. DI 50, ssi 30, and hit lightning 30 or sometin like that (spitballing from memory)
