The Soul of the Jungle is a new soul material in Avalon. It is only dropped by Jungle-specific NPCs(Except for the Corrupted Hornet), such as a Hornet, Little Stinger, Big Stinger, Man Eater, Snatcher, Jungle Slime, Jungle Mummy, Jungle Bat, or Queen Bee. They are only dropped after Oblivion has been defeated. This soul can be sold for 10 Gold Coins each, amounting to quite a profit when stacked to 250.
The souls are dropped in quantities of 1-2, but only at a 20% chance. These are needed in the crafting of Awakened Rose Armor.
