Is it really 27 pcs of 125 philo items? isn't it too expensive for pants alone?

I mean i understand if it's a two piece set, but nope it's only pants.

all the other vanya casting gear have 9pcs of these 125philo items but the pants needs 27 of them.

CRAFTED i70 PANTS ALONE COST A DARKLIGHT SET

is this intended?
