After reading the response I realized every option had haste on it. Oops. I also eliminated the last suggestion, as it seems +4 is simply not going to happen, regardless of how rare the item might be. I have a few ideas for some legendary dire bear gloves. Here goes:
Option 1 Ingredients:- 2 Legendary Dire Bear skins
- 10 essences of speed
- 3 oils of sharpness
- 5 nuggets of cobalt (for the claws)
- 1 cloth pattern
- 1 spool of thread
Properties: +3 Attack Bonus, +1D4 Slashing damage, Haste twice per day
Exceptional: +3 Attack Bonus, +1D8 Slashing Damage, Haste four times per day,
Option 2 Ingredients:- 2 Legendary Dire Bear skins
- 10 essences of speed
- 10 essences of wisdom
- 1 emerald enchanted with owl's wisdom
- 1 cloth pattern
- 1 spool of thread
Properties: +3 Attack Bonus, Haste twice per day, +4 ki strike (feat)
Exceptional: +3 Attack Bonus, Haste four times per day, +5 ki strike (feat)
This may not even be possible to make in the toolset. I don't know if this feat could even be added to an item, but it would make them a little less powerful than a straight-up AB of +4 or +5.
Option 3 Ingredients:- 2 Legendary Dire Bear skins
- 10 essences of speed
- 10 essences of grace
- 1 emerald enchanted with cat's grace
- 1 cloth pattern
- 1 spool of thread
Properties: +3 Attack Bonus, +2 DEX, Haste twice per day
Exceptional: +3 Attack Bonus, +3 DEX, Haste four times per day
or +3 Attack Bonus, +2 DEX, Cat's Grace(2) twice per day
Option 4 Ingredients:- 2 Legendary Dire Bear skins
- 10 essences of speed
- 10 essences of sight
- 1 cloth pattern
- 1 spool of thread
Properties: +3 Attack Bonus, Haste twice per day, True Seeing twice per day
Exceptional: +4 Attack Bonus, Haste four times per day, True Seeing four times per day
Before dismissing this idea out of hand, consider that the exceptional gloves would be EXTREMELY rare, and that gloves, unlike melee weapons, cannot be enchanted by mages or clerics with enhancement spells like Greater Magic Weapon, or darkfire. Make the lvl req. at least 21st lvl, and you wouldn't need to worry about them being worn by too many folks.
Ok...four options for your critical pleasure....
