How about the first useful overspawn drop since the rewrite!
Mystical alloy sword
Level Req: 15
Damage: 7 to 78
+35 Intelligence
+2% Parry
+6% Lightning Mastery
I was pretty happy with that one when it dropped

Oh and this one.
Magical diamond dagger
Level Req: 40
Damage: 82 to 143
+55 Intelligence
I also welled this before overspawns were possible and even though it's magical... I still use it. Haven't been able to upgrade to a rare+ somehow
This one's pretty far down but... 29 out of 25 int at lvl 10 is pretty good.
Mystical steel longsword
Level Req: 10
Damage: 13 to 131
+29 Intelligence
+1% Lightning Mastery
+7% Wind Mastery
Now that I look back at these... I'm starting to think that int weapon drops are my thing. Maybe I should do some lvl 55 staff mute/welling and see what happens
Oh yeah, I also own this, but I didn't find it:
Rare heal XI
Level Req: 40
Heals: 51 to 138
Mana Cost: 85
+55 Dexterity
+1 Critical Strike
Anyway, Rex... I think multi-property items are more interesting to look at than perfect ones. You should make the next post a super confusing one where you ask people to post items with multiple useful high tier properties so we can really see some crazy shit
