To improve protection, you need to go to Dawn Island, because there are no walls on it that can block your path. Set a respawn point on the island, and then turn on the macro. Now your character will automatically fall into the water, taking damage and increasing protection. To achieve this goal, you need to use the «phoenix fruit» - by eating it, you will receive water damage. It is important to remember that fruits such as «Ice» or «Magma» are not suitable for this pharma.
