it can happen, that is why you should be careful when you play gatcha
because it is also like gambling

it is all random things.
I heard rumor of wearing LK+DA eqs for 4G but somebody needs to proov
it because one of my friend also said that the rare item thing became
rarest after 1 year ><" and also when you play gatcha do not enter
a town with mycamp items and wait for Special town always =)
and use 2 gatcha drills to get rare eqs ^^ so that you do not get junks.
in last Special town I got 2 capes,1 gun, 1 staff(fused and sold it)

all from saved up end month free gatcha coin offers ^^
anyways good luck next time.
D: Trickster screwed me over, I gacha'd only to receive my camp items. Terrible stuff.
