How to Upgrade your Weapons and Armor by hunting.

A good reason why a lot of people hunt because they want to upgrade their tomestone weapons and armor. Hunters can collect seals and nuts to purchase upgrade items from vendors to get that extra boost to help clear those raids and new content. In clearing savage tier raids you can also obtain the items needed to upgrade your tome gear as well. Upgrading items got better much better 6.0. Instead of two pieces of random gear dropping from two coffers, players receive 3 specific gear coffers, upgrade items, and books. These coffers are of specific types; such as rings, weapons, chest piece etc. When you use the coffer they become their corresponding armor, accessory, or weapon based on the class you are on, so be careful when you open them. The drops for upgrade items in the savage dungeons have changed as well. The second fight of each tier drops upgrades for accessories, and the third drop upgrades for armor and weapons. Each fight also drops a unique book that can be exchanged in various quantities for armor and upgrade items, more information is listed below. There are four fights for each tier of Savage Raids. The 6.0 raid is "Pandamonium", so the raids are listed from P1S to P12S. Each time a new raid tier gets introduced, a new item level cap is introduced for gear. 2.0 Turn's 1 through 5 (this is the exception to the rule) max i-level was 90; 2.0's top i-level was 120, 3.0's top tier was 270, 4.0's top tier was 400, and now 5.0's top tier for gear is 530. The earliest and primary source for upgrading your tomestone gear is getting the upgrade items or books in sufficient quantity from the savage raids. The secondary source is hunt currency. This becomes available at a later patch after some time has passed, typically when the 24-man raids become available where you can also obtain a coin, the third source of upgrading gear, that can be exchanged for upgrade items.
