QUICK GUIDE:-

LEG 1
Ward of Regret - http://img3.wikia.nocookie.net/__cb20130704120050/dragonsdogma/images/a/a0/Map_Ward_of_Regret.png

Chest #3 & #10 contain high chance level 3 Gear.

Midnight Helix - http://img2.wikia.nocookie.net/__cb20130708204020/dragonsdogma/images/d/dd/Map_Midnight_Helix.png

Chest #8 & #13 contain high chance level 3 Armor.
(If one doesn't show after a few godsbanes, walk to the other and godsbane that one first)

LEG 3
Forgotten Hall - http://img4.wikia.nocookie.net/__cb20130704160507/dragonsdogma/images/d/dc/Map_The_Forgotten_Hall.png

Chest #9 has Armor 3. Godsbane.
Chest #15 has Gear 3. Godsbane.
Chest #16 has Novelty 3.

Bloodless Stockade -http://img1.wikia.nocookie.net/__cb20130704161146/dragonsdogma/images/7/78/Map_Bloodless_Stockade.png

Chest #4 contains Gear 3. Godsbane. Requires a skelton key
Chest #12 holds Weapon 3. Don't godsbane, but open it everytime you pass through here. Man eaters sometimes dwell in this chest.
Chest #15 has Gear 3 also. I don't godsbane this one but if you're desperate....

Sparyard of Scant Mercy - http://img3.wikia.nocookie.net/__cb20130703211548/dragonsdogma/images/a/a0/Map_Sparyard_of_Scant_Mercy.png

Chest #5 is a host of goodies. W3, G3 & N3. I usually settle for the gear!
Chest #6 also has tasty things. A3, G3 & N3. Again I'll take the gear.
Godsbane is worth it on both these.

Fallen City - http://img2.wikia.nocookie.net/__cb20130703210626/dragonsdogma/images/6/6e/Map_Fallen_City.png

Chest #13 has Armor 3. Medium drop rate. I don't godsbane this one.
Chest #19 has Weapon 3. Very small drop rate. Don't godsbane.
Chest #10 contains Armor 3. Save infront and dive off the cliff nearby to save time. Its faster than godsbaning!

Bitterblack Sanctum - http://img3.wikia.nocookie.net/__cb20130617082201/dragonsdogma/images/2/2d/Map_Bitterblack_Sanctum.png

Chest #1 has Weapon 3. V high chance but I save infront of it just incase and godsbane when I rarely get RC.
Chest #3 has Armor 3. Same as above.
Chest #4 has Novelty 3.
