1 week would be quite rediculous for 2 phases of 100 floors a piece.

As for what you need for Gambit: Slayer cards, leveled to 100 for maximum effect.
Also, lots and lots of peronamin helps to make it to the end. Especially phase 2 can really drain your stamina.
Glasses work too.

Remember that there's also a Slayer card in the regular nGacha.

Level your Slayers to 100 as soon as possible. Even before you start playing the event, if you can.. This is why it's always a good idea to have 150-200 levels worth of SR Wildcards and R Wildcards in your inventory: to use them on the Slayer cards the minute you get them. Most events easily earn you back all those slayercards and plenty extra, except maybe Shards.


Don't waste glasses on the random tokens during phase one, unless there's an exclusive reward for your phase 1 ranking (gladly never seen that happen).

The last door on phase 1 and the last 5-10 doors on phase 2 are random picks, one out of six (other doors have better odds). So it's a good idea to always keep enough glasses in your inventory to at least open those (or, bring more peronamin so you can just keep trying!)

During the event, you usually get pink keys when buying nGacha tickets (costs pero, not Nutaku gold). If you can afford it, buy enough gacha tickets to end up with more than a thousand pink keys. As long as you have more than 1,000 pink keys in your inventory, the weakest guard will always drop a pink suitcase instead of a pink key. At least, that's how it's always worked, pray they didn't change that.

You can turn OFF the Pero Radar thingy, simply by clicking the green beacon thingy in the top right corner while in exploration mode. Just in case you want to save your radars for Phase 2, when you get additional slayercards and a way higher multiplier because of that.

My tips
-Remove inactive (10+ days) friends. They can't open your chests and you cant open theirs. Try to avoid people with certain people who open up all their pink chests. I had someone who was opening around 95% of mine so I removed him.
-Save namins till phase 2.
-save egacha till phase 2. You'll be able to get twice as much out of the alphas since they will be betas for next event.
-save glasses for phase 2.
-Only use glasses on 5 step ups. Don't use them to advance stages since your sacrificing at least 100 of w/e things were collecting each time.
-If you get to a battle and you don't have the focus to kill it you can just close the explore window and wait till you do. It will still be there whenever you open it back up.


Pro tips
-Don't sleep and open lots of pink chests
