OK, whew. This was almost going to be a sad story, however, right at the end there I pulled it off!
I'm somewhat of a hoarder. My thought process is when I need something, I'll have it at the ready. So, finally time to make a new pet. No problem, I have oodles of uniques, I'll just roll one up real quick.
NOT!
Unloaded just under 3 tabs of any hero uniques. NOTHING!
Reached into my main heroes' uniques: Captain America, Jean Grey (benched for now btw), Juggernaut, Scarlet Witch, Captain Marvel, Doom and Iceman (also benched). That was about at least 4+ ish tabs in total...NOTHING!
Now I'm getting super nervous and sad at this point.
Starting from Cable and working my way down, I started picking up the uniques I collected for those heroes as I leveled them. Each hero had only a handful per each, maybe, 8 or so.
Picked out uniques here and there all the way down to night crawler.
AND BOOM, +3 Fighting Pet Roll.
Whew!
UPDATE: OMFG, I found a pet with +3 Fighting I wasn't using, lol...darn it >< :P
