That's the way to do it if you can, but I needed to get Horse Chestnut, Mistletoe, Soapwort, and Apple to the field ASAP for the RB event
The only one I got sitting there is Aconite and she is no where near the time that she needs ampy since she needs RG before she sees any action
I would like to pick up Wolfberry for future (she needs bloomed)and I will leave her down if I get a chance to get her.
I really hope they make this offer again...I got need for many
Another idea is to bloom Iberis and level her up with ampy, but I am not doing that because I don't see using her as anything as a support girl to bring in for skill/hit color needed/miss% girl in the future.
