Unique Item Level

I just found a unique item today. I selected a five star titan item to forge it and it’s stats went up by about 25%. I though unique items had power levels equal to your current ascension level and forging them reset their power values to your current ascension level. How does all this work? Is the value when you find something for the first time less than your current ascension level? A bit confused here… :slightly_frowning_face:  

when you get a new unique it’s not upgraded to your current level for whatever reason.

Do you know how many levels below your current level or does that vary?

Is it from a brand new or old chest?

(I still have some unopened Titan Chests from last month…)

It was from the HOLIDAY CHEST for Xmas.
