Last one for the Frog Girl
Alot of you might stuck on Just Budget Crisis. For the last one from all of her Sub event. Just to do Akko her last fight and watch her episode for this Achievement. There here’s the way to grind
Fun Fact
You found out that Shopkeeper (Chumlee) at Roundabout. And he just put Pollux Coin in his store. Right after you done this quest.
It’s 10,000 per Coin. If you manage to timelap days and nights then get running to check his store before you start grinding
- Reloading save file in just only one day with out timelap doesn’t change item cycle in the store
 - He stay around 10:00 AM to 6:00 PM (18:00)
 
Step 1: Set Game Difficulty
With higher Difficulty, there will be more mob spawn in the zone with more loot drop rate
I recommend you do on 
- Very Hard with high mob count and even more drop rate.
 -  Easy Slowest way you can grind with lowest 
mob spawn and loweest drop rate. - Normal Less mobs in the zone with less drop.
 - Hard Reasonable drop, for slow Grinder guy i guess?
 - Inferno If your skill set still weak you there’re More time consume. Facing more Big monsters count, in one zone .
 
It’s also good to mention that if Quest fail you got just exp and notthing back with you. So choose Difficulty as your Character & skill power that you can output at that point, that make you feel run smooth both Mob clear and melting bosses.
Step 2: Key Selection
Key Lv Recommend
- Lesser key of Pollux Lv.1
 
Higher level key, Mobs loot pool will be more than just Pollux Coin. So you get less Coins than your suppost be on one run.
Step 3: Character of Choices
Here’s from highest to lowest base luck
- Lotte Drop Luck 15 (Base Luck 14)
 - Akko Drop Luck: 8 (Base Luck 6)
 - Sucy Drop Luck 7 (Base Luck 9 )
 - Diana Drop Luck 7 (Base Luck 5)
 - Constanze Drop Luck 7 (Base Luck 5)
 - Jasminka Drop Luck 7 (Base Luck 4)
 - Amanda Drop Luck 6 (Base Luck 3)
 
It’s a good idea to pick Lotte and build her even more Luck, with her the highest base Luck So you can build stats easier.
Step 4: Recommend Spell
There’re alot of powerful spell you there so you didn’t need any Character Spesific Spell, Signature Spell Cutsence spell. What ever you guys call it. With this way you got less time waste waiting cutsence to finish on grinding.
Highly Recommend Spell
-  Rapid Fire (Page 6: Erdanus) Barrage homing balls that’s hit like a truck

 -  Gravity Blast (Page 5: Serpens) Fast cast large aoe line
 - Meteor Crash (Page 6: Cetus) Obtain by max Flare of Spash (Page 5:Crater)
 
Utility Spell Recommend
-  Icy Dawn (Page 5: Lupus) Fast cast large blob of ice, slow continues damage also work as a wall for a while
 -  Steel Wind (Page 5: Lyra) Force enemy to drop loot, really low damage
 - Steel Wind (Page 5: Lyra) Pull enemy back in to the screen (some of them went off the map and that’s Surk
 
Budget Crisis Reward

Tips & Tricks
- It’s even Possible to get from No drop to 11 Pollux Coins on just one Run.
 -  Besure to look out for Bags item that drop from mob 95% of the time contain your Pollux Coin.
 - If Bags drop out side the screen near Door to the Next Zone besure to just stay close and wait for magnet to pull stuff for you before process to the next zone.
 - You don’t need to expect much from Boss drop. tThey ain’t drop Pollux Coin that often. Mostly just there’re own loot pool like Minotour horn, Raging bull horn or Lance stuff.
