Amulets

Amulets have one primary offensive use for the bowazon: life and/or mana leech. The other stuff — +10-20 AR, +damage, +6-9 dexterity — is nice, but for the most part, it's all about 2-3% life leech or 3-4% mana leech. The assumption here is that leeching amulets will be used. Aside from this, amulets are primarily reserved for defense against the elements, attribute bonuses, and +skills.

Rare amulets are an excellent option; the most favored are +1 skill (or +2 to a single tree) amulets with prismatic and leech. Other attributes — one or two high (31-40%) resists (8-11% prismatic is nice), +41-60 life, +41-60 mana, 21-35% MF, +skills when available, triggered spells (direct-damage skills like Chain Lightning or Ice Blast that activate upon striking doesn't work with bows) and remedial attributes like Thawing/Warmth or 25-75% poison damage reduction — are up to the preference of the player.

• Civerb's Icon Amulet: replenish life +4, regenerate mana 40%, rlvl-9. This amulet has the highest amount of mana regen you'll be able to find for quite some time. If your bowazon uses high mana skills and not enough mana leech, this could be a viable solution until you can make up the difference elsewhere.
• Nokozan Relic Amulet: 20% faster hit recovery, fire resist 50%, +10% maximum fire resist, adds 3-6 fire damage, +3 light radius, rlvl-10.
• Eye of Etlich Amulet: +1-5 light radius, +1 skills, 3-7% life stolen per hit, adds (1-2) to (3-5) cold damage @ 2-10 seconds, +10-40 defense vs. missile, rlvl-15. This is perfect for low-level bowazons: low level requirement, +skills, cold damage, and life leech all rolled into one package. An Eye with 7% life leech will have more life leech than any rare amulet. A good bowazon or dedicated frostmaiden can use a good Eye for her entire career. Because of the possible variations, look after leech percentage and the hidden 2-10 second chill duration, one of the longest of any item in the game.

The Eye of Etlich has a hidden 2-10 second cold duration. The cold duration on this amulet will combine with other cold attack spells, so you can, for example, get a Freezing Arrow that lasts 3 seconds on Hell Difficulty with a 10 second Eye of Etlich. Remember that cold durations are 1/2 in Nightmare, and 1/4 in Hell Difficulty.

• The Mahim-Oak Curio Amulet: +10 defense, +10% enhanced defense, +10% bonus to attack rating, all resistances 10%, +10 all attributes, rlvl-25.

Rings

Like amulets, rings have one primary offensive use for the bowazon: life and/or mana leech. The other stuff — +100-120 AR, +damage, +6-9 dexterity — is nice, but for the most part, it's all about 3-5% life leech or 2-3% mana leech. The assumption here is that leeching jewelry will be used. After leeching, rings are primarily reserved for defense against the elements.

Good attributes include one or two high (31-40%) resists, +31-40 life, +41-60 mana, 10-25% MF, and remedial attributes like Thawing/Warmth or 25-75% poison damage reduction. Dual leech jewelry is desirable (and extremely hard to obtain), but in my experience, a character with two excellent pieces of single-leech jewelry is much better off than a character with two mediocre pieces of dual leech rings.

• Nagelring Ring: magic damage reduced by 3, +50-75 attack rating, attacker takes damage of 3, 15-30% better chance of getting magic item, rlvl-7. Nagelring offers the highest %MF you can find on a ring. As always, the returned damage won't work with ranged attacks.
• Cathan's Seal Ring: 6% life stolen per hit, damage reduced by 2, rlvl-11. While it used to be easy to find a good life leech ring (pre-LOD), rings that leech up to 6% life per hit aren't available for the bowazon until clvl-40 or so. They are extremely easy to find, and for the beginner bowazon, this is an excellent option until something better comes along.
• Manald Heal Ring: 4-7% mana stolen per hit, replenish life +5-8, regenerate mana 20%, +20 life, rlvl-15. The replenish life is close to the maximum amount of life regeneration a ring can get (+6-9). The mana leech is higher than anything you'll be able find on a rare ring for quite some time. The extra mana regeneration isn't really that helpful to the amazon's relatively low mana pool, but every little bit counts.
• Stone of Jordan Ring: +1 skills, increase maximum mana 25%, adds 1-12 lightning damage, +20 mana, rlvl-29. The increase in mana is added with other items that increase the maximum amount of mana, so two Stones of Jordan would increase your base mana by 50%. If you're running with a magezon, this ring is great, but I'd prefer to use one ring with a high flat bonus to mana and a single Stone rather than two Stones.
