760 Adventure points for a slot 3 earring is a sweet deal. Especially when it already comes with some INT, WIZ and CHA on it to start with and 2 of the hardest saves to raise on it.
Drop in a Furry of Druzzi (Enchanters), Spell Haste 4 or FT1 augmentation in that type 3 slot and things start to look interesting.
I plan on putting Spell Haste 4 in this so I can swap out my ornate boots for some flowing slime FT3 goodness to max my FT to the cap and free up my FT2 belt slot for Improved Damage 4 belt.
