We promise your level up
We intended to use this expression to draw a particular crowd as an ads of an institute(or a cram school called "hakwon").
I'm asking this of you for a school assignment with my group in college. Sure, there's a lot of items for this. The problem is I think it's a wrong sentence, but all but me think it is good. So we planned to submit our assignment for that phrase. I posted this question for persuading my members lastly into using other units for a reasonable reason.
"We will bring your level up" or "we will get your level up" feels just fine. Even though I know this structure like "promise sth to sb" is possible, but I feel like "your level up" is not compatible with the verb "promise" as an object, because there are phrasal verbs like bring sth up or get sth up, but there isn't a thing like "promise sth up". And I googled the phrase "promise your level up" but 8 came out in search results. So I think it is wrong. What about you?
