Really, a perfect item depends on what you need it for, and what mods you prefer. Malice's example is pretty much what would be considered a perfect sword, though some might prefer a +5 energy (zealous) mod in place of the +30 HP mod. Others might prefer a vampiric blade instead of a sundering. It just depends on where your intrests are, and how you play.
And to translate the jargon;
Quote:
Low req (7, 8 or 9)
15^50
20/20
+30hp
|
Would be a sword with;
- 15-22 damage (max for a sword)
- A requirement of 7, 8, or 9 swordsmanship
- A 15% damage increase while health is above 50%
- A 20% chance of 20% armor penetration ( a best quality Sundering mod)
- and +30 health points (a best quality Fortitude mod)
To be considered 'perfect', it would probably have to be gold. Though really, I think that the term perfect just depends on having; max damage, a requirement of 9 attribute, and on Prophices and Factions drops a 15%^50% mod. Anything else can be modified, and with Nightfall introducing inscriptions all you're really looking for would be max damage and low requirements.
As far as a staff, you're looking for about;
11-22 damage
Requires 9 (or lower) attribute points
+10 energy, always.
Halves Casting time of attributes spells (20%)
Halve Recharge time of attributes spells (20%)
And then staff heads and Wrappings of various quality, such as +30 HP( I use a staff head and a staff wrapping that give me +60 hp), Items attribute +1 (20%), and other mods that give you more energy or more armor.
