Gem Farming

Chapter 20 is a normal difficulty chapter. Players can win this chapter using high attack damage, high armor rate and high evasion rate.
Actually chapter 20 is a good choice of gem farming before chapter 27. Players can win chapter 20 with their favorite chipsets combination easily and merely lose one life in this chapter.

The average gem reward is still high enough compared to higher chapters.
If players have confidence in challenging higher chapters, they might try gem farming in chapter 23 or chapter 24 since these chapters have 17 waves.
It is suggested Build Body upgraded to BN Unit-5 and Turret Buffer drone upgraded to at least “Rare” grade in this game progress.

Recommended chipsets: Aiming Lens, Vibrating Module, Rifle, Laser Eye, Turret Module, Gun Turret, Beam Turret, Spiral Barrel
