Battle star rating effect on drops in FFXII-2

Question

Is there only an effect on drop rates in final fantasy XIII-2 with 5 stars?

You just see an increase listed with 5 stars but I thought there may possibly be an alternate effect for stars 1 through 4.

Answer 1

If you get 5 stars in a battle it increases your drop rate by 200%. Anything below this doesn't affect natural drop rate of a battle.

However, you can equip a Collector's Catalog which can be won from Chocobo Racing in Serendipity which increases your drop rate by 20%.

There is also the Durable Catalog which increases drop rates even more (120% for a rare drop and 300% for normal item drop) and you can also use a Silver Chocobo which will have `Item Scavenger 2' which increases item drop rate by 150%.

These aren't stackable though: meaning your best option is to get the Durable Catalog

Answer 2

I have the DLC Valhalla Lightning Lv.13 with Gilfinder II, Item Collector, Item Scavenger II,

Item Collector:Increases the odds of obtaining rare items after battle. Item Scavenger II:Increases the odds of obtaining items after battle. Gilfinder II:Increases gil earned after battle.

She is basically another Collector Catalog. lightning in party with Noel and Serah both wearing the Durable Collector Catalog All the gilfinders stack so you will get alot of cash.

not sure about the items though.
