Capture Dangerous Beasts
You can capture any beast you find in the World of Wraeclast when you receive your training. As you become more skilled at hunting, you’ll be able to capture legendary creatures. You should track Wraeclast's most dangerous animals, weaken them, and capture them to make them of your own. There are about 250 regular beasts and 40 legendary beasts to capture.
Complete your Bestiary
Every creature you’ve caught will be recorded in Bestiary, and a detailed book contains information about the beasts. As you capture beasts from Wraeclast, they are marked in your Bestiary. This is a permanent record of your progress in this league.
Populate your Menagerie
You should visit and observe the beasts you've captured whenever you want, then use them to fuel your beast crafting. You will receive your own menagerie which you can populate the beasts you’ve captured. It looks like your personal zoo with some crazy creatures that want to hurt you. You can keep them on display to show off, or you can get them ready for the fun part.
Players can perform the ritual of Sacrifice by combat at the Blood Altar to create and augment potent items. There are dozens of powerful recipes which require sacrificing different combinations of beasts that you have collected. Here, players can be allowed to sacrifice their captured beasts to the Blood Altar to create powerful new items. Beastcrafting recipes will require various monsters, so you’ll have to get out and hunt if you want to craft the best stuff. Then you’ll be able to craft gems, flasks, and more.
New End-Game Foes
Capturing and crafting with the right set of beasts may make you enter into difficult spirit boss, and meanwhile you can also get powerful PoE exalted orb and other items rewards.
The Bestiary League involves four new sets of items based on the powerful spirit beasts. You should mix and match them with other items, and you may discover potent new builds. Once you’re ready, you can craft a Spirit Land portal to hunt one of the four Spirit Beasts. These guys are tough, so make sure you’re prepared. If you can beat them, you have the chance to get some rather unique items. Now let’s see some questions that players may encounter in PoE Bestiary.
