Last cave key was weeks ago, how can you not have 1050 keys by now (Or by Wednesday next week, if Cave Key comes online on Thursday)? What are you spending your moon coins on?

Events like Cave exploration rebates are fixed, meaning they are always happening in the same order.

1. Charm rebate

2. Refining rebate

3. Recruitment rebate

4. Cave exploration rebate

Then repeat. So it will happen on Thursday, because it is the time for it to happen. But you have time till next Wednesday to get 1050 keys

You have two weeks worth of moon scrolls to get cave keys because the rebate ends on next Wednesday. This should be enough for a couple of hundreds keys, just don't spend on other stuff and get the maximum for the week.

i still only have 500 cave key new server plz just wait 1 more week

As said before, these events are fixed.
Either try to get keys, or wait another month and do a 2100 keys rebate.

Hah see its charm thanks oasis (plz don't change it)

Im on your exact server man but i have easily got 1050 keys infact im almost on 1150 so wasent really that hard.

Only those who know nothing about rebates dont have 1050 keys yet...

Wait so it would mean its :
1. Charm rebate
2. Cave key rebate
3. Refine rebate
4. Summon rebate ?

Since this thursday is a charm rebate as u mentioned, but on your list cave key is 4th and u said key rebate is next thursday? Im confused, I would be thankfull if someone would explain.

As for the order of the events, it's getting harder to track since they move around events earlier or later. You either just add 3-5 weeks onto the current rebate that showed up for its next appearance or predict the next rebate based on the last appearance.
