Exalting an item with the 'prefixes cannot be changed' mod.

Scenario:

Rare item with:

- Prefix one
- Prefix two
- open
- suffix one
- suffix two
- prefixes cannot be changed

Can you still exalt this item? I asume so since you are adding/generating a stat and not changing it, but would be nice to know for sure.

If not, u could craft some crap suffix with master, exalt, remove crafted mod and ad meta mod.
