Guide:Completing the Bestiary

This guide describes how to complete 100% of the Bestiary in one world without bringing anything from another world and assuming you go through a classic Walkthrough and you are in a world created in 1.4 without special seeds and not in holidays.

= Early game = The early game is quite standard, you don't have to do anything special and you way want to get gear to continue. You will just have to defeat every pre-Hardmode bosses and crush at least one Shadow Orb or Crimson Heart to trigger the Goblin Invasion.

= Getting the other Evil = You will need to get some Crimson in your world if you are in a Corrupt World or some Corruption if you are in a Crimson World and it should be easier to get them while you are still in pre-Hardmode

The Cemetery
To complete the Bestiary, you will need the other evil in your world. To do that, you need to gather at least 6 Tombstones created after your deaths or after your NPC deaths if you are in Hardcore. Place the 6 tombs around the Dryad to buy her some Corrupt Seeds/Crimson Seeds. If you didn't beat them already, profit being in a cemetery to kill some Ghosts, Maggot Zombies and Ravens. You will see some Maggots spawn after killing the Maggot Zombies and some Rats while in cemetery, walk near them to complete the Cemetery part of the Bestiary.

Other Evil surface
Now you have some evil seed, plant them in a place where there is a lot of uncorrupted grass, wait a bit and you will be able to gather some Vile Mushroom/Vicious Mushroom. You can now transform them in Thrown Powder to spread the evil even more. If you prefer Thrown Water, covert some sand with the powder so you will be able to make them. Keep some powder or water in a chest in case that your evil is converted when the Hardmode begins and beat the Eater of Worlds / Brain of Cthulhu

= Checking the rare creatures = Some rare creatures are even rarer in Hardmode so you should beat them before, you could increase your chances of seeing them by using a Water Candle / Battle Potion / increasing the spawnrate in Journey mode : = Early Hardmode = To be continued
