You can kill all 3 bosses in 1 week (assuming all 3 respawned, which may not happen).
But here are some very important points:
- When you kill a boss you cannot enter THAT teleport again, until you open his chest and make another CRATES (deepling phase 2)
- If you open 1 chest, you cannot kill any other deepling boss during that STAGE 3, you need to wait next STAGE 3 to kill another boss.
- Each Crates will give you permission to open 1 chest, after you open a chest you lose access to every boss teleport, doesn't matter if you killed or didn't kill it.
What those 3 points mean? They mean that yes, you can kill all 3 bosses in a row (if you don't open any chest after leaving boss room), but then you will be "owing" 3 chests.
I'll give an example, is easier to understand:
- Stage 2: You do Crates
- Stage 3, day 1: Obujos respawned. You kill Obujos. You DON'T open his chest.
- Stage 3, day 2: Tanjis respawned. You kill Tanjis. You OPEN his chest.
- Stage 3, days 3-5: Jaul respawned. You cannot kill JAUL because you opened Tanjis chest, thus losing access to every boss.
- Stage 2: You do Crates again
- Stage 3, day 1: Obujos respawned. You CANNOT kill Obujos because you killed him last time and still didn't open his chest, you "owe" his chest.
- Stage 3, day 2: Tanjis respawned. You kill Tanjis. You DON'T open his chest.
- Stage 3, day 3: Tanjis respawned. Since you already killed it day before, you cannot kill him now, so you choose to open Obujos chest.
- Stage 3, day 4-5: You cannot kill Obujos nor Jaul, because you opened Obujos chest, losing access to every boss.
I hope this example could make it clear, how killing more than 1 boss in a week can backstab you, you need to really think it through!
