I have not been able to beat it. I am now on level 69. He asked me for a 800k item. I bought it. Normally he asks for more. Maybe time for a revamp? I want to beat him at least once please

It's not supposed to be easy. It's also a one-time thing; you're not able to start over anymore

I spent roughly 100m on the last 10 levels. you don't beat item hunt for the sP profit, you do it for the achievement and weapon at the end.

I did not know that. Thanks for telling me. I don't want to finish it then

Me neither tbh, it's a good moneymaker. But if you do have any interest in battling, you can get Chase as a challenger if you quit at level 75+, he's I think an Impossible challenger? (idk too hard for me to fight at tier 7 and I've decided to stop training here so) but you're close to unlocking him if you ever wanted to c:

Yes chase is an inpossible challenger. He's middle to high tier 11 I believe
