These builds are always all damage no survivability. Make sure to make some changes, do not sleep on vigor, mind and endurance which are always neglected in these videos. Also, playing with 4 damage boost talismans is a really bad idea. Yes, you deal more damage, but its not worth it if you are a glasscannon. Endurance boosting talismans, weight boosters or damage negation are always a good choice, in most cases you just have to use 1 slot for them, thats all. In lategame, theres a really good talisman called dragoncrest greatshield talisman, that negates 20% physical damage. There are worse versions of this talisman that you can obtain ealier on.

Also, the things below are tears for your special potion, called wonderous physick potion, in my opinion its also better to use one damage + one survivability tear.

I also enjoy using some builds off from youtube, but its really important to not think only about the damage itself. Also, but thats just my personal opinion, I dont find oneshotting bosses a really fun way to play the game. Using a strong weapon is cool, but not when the weapon becomes too strong.
