To get Human V2 in Blox Fruits, follow these steps:
First, ensure you meet the requirements. Reach level 850 and have 500,000 money. Also, complete the Bartiloquest.
Next, collect the flowers. Find the Red Flower during the day on Foreign Island, Russo Apps Island, Cave Island, or the Graveyard. The Blue Flower appears at night on Russo Apps Island, Cave Island, or the Graveyard. Obtain the Yellow Flower by killing any NPC.
Then, head to the Green Zone and talk to the Alchemist. Bring all three flowers back to him to complete the quest.
Finally, enjoy the buffs of Human V2. These include increased movement speed, flash step range, cooldown reduction, extra dodge capabilities, and a longer dash distance.
