Seriously, though... Is it death?
Minecraft riddles
I am the strongest thing of all
when confronted with the weak, i destroy it
i turn the weak stronger
the weak now can destroy the strong
and i turn the strong stronger
what am I?
In guess maybe my awnser is a little specific so i guess johny got it right! I was looking for the player's hand (as in it destroys wood and wood can destroy iron iron can destroy diamond and diamond can destroy obsidian, so technically your hand is stronger than obsidian and has infinite durability.)
Another non-minecraft that could be in minecraft too if you think about it...
No man is fast enough to run from him,
No man is stealthy enough to hide from him,
No man is strong enough to fight him.
Who is he?
