Game player, go to the dragon's dogma wiki. After researching you will find that after the first time you beat daimon a type of "hard" version opens up. Stronger enemies, mobs are different (most areas will randomly spawn different types of mobs) Better loot drops (such as lvl 2 and 3 gear being more common) etc.
Normally I would stay out of petty squabbles but you were giving incorrect information and when someone contested you, you immediately assumed you were right they were wrong end of story. You did ask for proof, so I'm not bashing you, but the same could have been asked of you
To the other squabbler, maybe a more subtle approach to telling someone they're wrong can help. People can easily have their feelings hurt on the web, this leads to flame wars and derails topics.
