The x10 bonuses work a little weirdly, but you can manipulate them to your advantage. First we’ll talk about how to they work.
Every day, 5 of these bonuses regenerate. I forget the exact time, but its every 24 hours.
When they regenerate, they find a ‘slot’ to go into. If you complete every challenge with a bonus, these 5 bonuses will fill every slot. If you’ve only done say… two. Then those two slots will be filled, and the leftover 3 will be banked.
If you did no challenges, then all 5 will be banked. You can bank up to 30 at once, challenges banked after that are lost.
When you have banked challenges, they will fill any slot that is completed.
Now here’s where you can get the most bang out of your buck. Let the challenges accrue in the bank. You can go to 30 (takes 6 days), or you can start a little earlier. Now complete the challenges in the fourth and fifth slots (the two in the right hand side), if they are purple or gold. If they are not purple or gold, use one of your daily resets. Sometimes slot 3 will have a decent challenge, do them as well if you see them.
The trick here is to only use the bonuses with Purple, Gold, and if those aren’t appearing, Blue (to get a Purple or Gold to appear in its place).
When you complete them, they will reset and give another high level challenge and then get filled in with a bonus. You keep doing this until you run out of bonuses. If you do this with a fully bank of 30 challenges, you can easily go from level 1 to 25-35 (highest I’ve done is 46) in one sitting on your battlepass.
This allows players to complete their battlepasses in a little under a week in most situations.
There is only one downside to this method. It doesn’t work with end of cycle bonuses. Because extra bonuses are cut off if the bank is full, you have a chance of missing them. But you can still manipulate this as well. When FC announces they are going to give those bonuses, try to expend all of your bonus the day before. This way the next day they will fill up your bonuses and bank with x50 bonuses. Allowing you to complete your battlepass in 2 days tops (even if doing it on public servers). This is the method I use on my alt accounts.
