User blog:CeruleanGryphon/Preparing for Tower- what to spend money on?

Tower events are my favorites since I try to collect the wandering ghosts. The next upcoming tower I'd like to try for one of the 5* wandering ghosts and maybe even a ranking daemon. I'm currently trying to max out the few un-maxed defense reducers I have and allocating more points into health.

However, I'm curious about the magatamas that are offered as bonuses for 6-pack summons. How much of a boost do these mags give? I know there are small and medium boosts, but don't know the percentages that those boosts would give.

Should I invest in a 6-pack summon solely for the magatama that helps with the event or is it better to spend on remedies? I do not have luck with 6-pack RNG, so I am not expecting anything but 3* from it and won't summon multiple times so the gold apple is mostly useless too. My health at the moment is 220, but will plan to level and reallocate to get at least 240. At the moment I have 19 DN in stock with a dozen candies.

What are your suggestions? :)
