Where should my mesos go right now?

Hey yall, long story short, I got lucky with gacha and got a chaos scroll that I sold for 93 coins so that's the reason I currently have some money.

I'm not sure what the best way to spend it is, I have 2 characters, an Assassin 58 and a Cleric 51. Im thinking about getting the Cleric to Bishop through some leeching but at the same time I know that the Assassin is gonna be the one that needs the most leeching as I want him to be my main. I'm not sure when is a good point to kind of stop leveling the Cleric.

Both of them also need a lot of equipment upgrades, especially the Cleric. (He's struggling with equips cause INT equipment is so expensive.)

Also the cleric is going to be light wash if at all and the sin is gonna rely on HP Challenges.

I need some opinions on what to do at this point, how should I use the money I got?
