Jamew7 If you want to grind with buddha you must use Sword and Melee instead, don't use the fruit skills since Melee and Sword will become big and easier to hit enemy when you are in buddha form, That's why people call it the best grinding fruit in the game, Keep that Buddha and keep grinding with Melee and Sword with Buddha.
Light is good for grinding too but if you get in 3rd sea use buddha because the npc in 3rd use aura, usually npc cant hit elemental fruit like light but because of aura they can hit you, so i recommend use buddha
On my opinion fast fruit is not everything and when u say Buddha is the most mistake we did u just like disrespect the Buddha users and to the pro players know Buddha is one of the best fruit in the game man and the best grinding fruit
