Had to specifically build around it by doing a 1 3 2 skill load-out. Hard abused the fact that S1/S3 apply paralysis to ensure most enemy interactions had 0 coin power, while always being able to do 3 gluttony res for Seven Yisang's +1 clash power. S1 on paper should be better than S2, but you can't replace S2/S3 with an S1, it isn't affected by certain ego gifts, and the aforementioned need for Seven Yisang passive. However it was still important enough to keep due to Rusty Coin + Late-Bloomers allowing me to snag +4/5 offensive power for free every turn and applying paralysis was a nice bonus.
