The main features of 에타츠 헬퍼 include automatic hunting, log deletion, modification of hunting interval, automatic selling on the exchange, and automatic use of proficiency in the advanced inn.

With the "자동사냥 시작" (Start Auto Hunting) button, you can automatically start hunting on the main page after logging into 에타츠. To stop the auto hunting, simply click on the "자동사냥 종료" (Stop Auto Hunting) button, which will also navigate you to the "전투 손익명세서" (Battle Profit Statement) page.

The extension allows you to delete all logs of the auto hunting process with the "로그 삭제" (Delete Logs) button. Additionally, you can modify the hunting interval by entering the desired time in milliseconds and clicking on the "자동사냥 주기 수정" (Modify Auto Hunting Interval) button. The recommended value for general users is 9000ms, and for users of the "5-second hunting ticket," it is 4000ms.

In the exchange, you can automatically sell the items you own by clicking on the "전체 매각" (Sell All) button.

For the advanced inn, the extension offers the "숙련도 자동 사용" (Automatic Proficiency Use) button. By clicking on this button, you can automatically use your current proficiency to increase your stats.
