There are many +9 items already in Kronos, but with no history of upgrading.
I scanned around little bit and probably found the 1st legit upgrader in Kronos who made a Shard rev +4 to +11, Iron bow rev +4 to +9 + his armor FP +8 to +9.
That's some sweet upgrading.

Maxi and Pnb got their items on the second week :S
Many +9 items popped up out of nowhere in carnac-west too.
Warrior chitin shells +9, shards +9, any many more...
Are we really dealing with a GM who sells items for $ ? :O
