Ilse's Achievement Event Farming guide



The two main prizes for this event are the 100 crystals for completing 70 Titan Exterminations mission, and getting Nifa to at least 5-star.

Don't pass on Nifa. She is the best f2p unit (she is as strong as 5*), even having her 3-4* will be pretty strong
 * You get different amount of medals base on the stage you complete, and bring 5★ Ilse, Hitch,Petra, and Nifa for bonus tickets (max 210%)
 * The best stage to grind for bronze medal would be stage 7 (The first stage that cost 100 scrolls), you get less bronze medal on the above stage, but more silver and gold medals.


 * To get more Titan Extermination clears, you can choose the lower level ones that costs less special instructions. Titan Extermination #1 only costs 50. This can be useful if you're short on hitting the 70 clears.
 * To get Nifa to 5-star, you'd need medals. The best way is to pump as many bonus characters as you can to increase the medal reward after each completion. If you're short on special instructions to start the fight, you can spam the skip tickets onto low-DP stages as each stage gives you around 3-5 special instructions.
