1. Insight:
As a part of improving mercenaries overall and Act 1 Rogue Archer particularly, Blizzard decided to allow making Insight runeword in Bows and Crossbows. That also should make elemental Amazons to level up easier.
2. Plague:
Great runeword for Act5 Barbarian Warriors when hired by players with Rabies or Plague Javelin skills - Lower Resists curse is the only one that lowers poison resistance. Also it is great alternative if player doesn't have runes for Infinity.
3. Pattern:
Starter claw, good to level up melee assassin since they received a buff as well.
4. Mist:
Good bow if no runes for Faith, but might be better to save Cham for Pride.
5. Unbending Will:
Very cheap runes inside, can use in Executioner's Sword as soon as found on Nightmare difficulty (will get 6 sockets from Larzuk's quest). Probably, Blizzard created it to use by Act5 Barbarian Warriors but Taunt doesn't look much useful.
6. Obsession:
Great alternative to many sorceress items, only problem is Zod rune. But if you found a Staff with +3 to one-three skills that you use, that means you've got +7 total while Heart of the Oak + Spirit give only +5. And you don't have to invest mass strength to wear Monarch.
7. Flickering Flame:
Can be good when you need fire resists and using Fire skills on same time, for example when using Spirit shield.
8. Wisdom:
Looks like useful starter item for Bowazons. Offering piercing attack till Razortail is found. Cannot be frozen and Mana leech are good bonuses to that.
