User blog comment:CeruleanGryphon/Preparing for Tower- what to spend money on?/@comment-10777624-20130809231036

Last event I had two magatama helping me; I had an additional acquisition that I think was small that increased my additional stardust by 5%. I also had a medium discovery magatama that increased my discovery by 3%.

The additional acquisition was the first one I had and had throughout most of the event and it rarely activated so it was pretty much useless.

With your health, I don't see why you would need to invest in many remedies as you would have more investigations per full health. If you did a six pack, it would be possible to get the encounter rate mags that boost your chances to find wandering ghosts so maybe one six pack would be a good investment. And who knows, you might actually get something good out of it this time. :)
