New monsters are showing up in Shrewdo relic, a stage far bigger than the last. Some of the monsters are almost immune to some type of attacks so you have to bring various types of guns in order to deal with the creatures.

The boss G-Spider is immune to optical and electric attacks so it's mandatory that you use physical type weapons. And you are advised to form a squadron with different types of guns for the enemy force is huge. Most of the monsters here drop items below v4 level but some drop items of v6 level.

If you go to the Sub-Stage through the Link WarpGate, you will be able to meet a merchant providing special tuning.
