The Addition to get Medals from this Core Stages is definitely a Welcome one. I farm the one with the Ratio 80 Stamina/700 Medals per run.
Still kinda slow but better than the last stage with the Pest having so many guts and Health Regeneration. Only team i can use for this includes Sigilaria and here i think Sigilarias weakness shows. You dont want to seal Health Regenerating Mobs. It is bad. In General the Seal Ability i think is a Double Edged Sword.

Anyway as much as i complained about the Powercreep and the changed Schedule of of the limited Units lately re-released, i very much welcome the devs decisions to implement a good opportunity to finally farm High Ampules now reliably!!! Before this getting High Ampules was a huge pain in the butt.

Also i got a Second Cotton??? No idea where i got here from. i must have overlooked something but a Dupe of her i am ok with cause i rate her quite highly.

Now i think its best going for Stamina Refills with the World Flower Exploration
