1. Synthesis through gorilla armor drawings: You can find or buy the corresponding gorilla armor drawings in the game, and use the drawings for synthesis when there are enough materials and in-game currency.
2. Reward through game activities or tasks: Activities or tasks are often introduced in games. By completing these activities or tasks, you have the opportunity to obtain orangutan armor or related props.
The specific method of synthesis or acquisition may be different according to the game version, updated content and the arrangement of planning activities. So I suggest you consult the official channels of the game, or communicate with other players in the game to get the most accurate information.
