I went with the unbound runes and gotten a 800 bp boost from it, you may get more depending on your summon level. I started getting charm packs once I max out claim the unbound runes. you can go for masked man if you are close on getting him, like 1-10 frags left. Fishing mania you can go for unbound packs too, but you c*so go for med runes if you are needing some to level up a refine. Time limted shop...... just go for summon scrolls.
