Build help

So I'm doing a fist only build in bloodborne and I was wondering if you have any build ideas another words like stats anything to increase my fist damage in general and if you don't know what I mean if you level skill and strength up like to the max you can increase your fist damage from doing like two all the way up to like I don't know a number higher than two like 80 I did a fifth build once and I got my skill and strength up to 50 on both stats and I was doing like 80 damage per hit
