Siege Level??
 

Hi,
Is there any way to determine the level of siege weapons?
I've been collecting low level coldfire, but they don't stack and they're becoming a pain to manage.
I tried advanced filters, and it lets me at least narrow down like level 10 to 20, etc.... but I would like to determing their actual level somehow.

If advanced filters can narrow it down to level ranges, then there is likely an exact level in the item data.

Check the tutorial threads, about eso updates. They contain a EsouiDocumentation_Pxx.txt

Inside you'll find the api functions like
GetItemlink(bag, slotid)
And GetRequiredItemlevel etc. functions which can be used with that item link.

AdvancedFilters uses these functions to determine their level.
Stacking is not only about the level though. Could look the same but one is from crown, other from loot, other is crafted. All the 3 might not stack though as there itemid is different, or other data is different.
