what does human v3 do in blox fruits

In the game Blox Fruits, Human is one of the four races that players can spawn with on joining the game for the first time. When players choose the Human race, they have no buffs except the utility ones. However, the Human race has a great damage level while gamers use the Last Resort (from 50% hp or lower) . According to a Reddit post, the Human races damage buff is a combo system, meaning the more consecutive hits a player does, the more the damage percentage buff increases. In some YouTube videos, players demonstrate how to upgrade the Human race from V1 to V3 by completing quests.
