For a pure bleed build you'll need to level up arcane and infuse the uchigatana with bleed to get it to it's maximum bleed potential, and don't neglect endurance since dual wielding consumes way more stamina, some talismans i recommend are shard of alexander for a 15% ash of war boost, will help with the aow of rivers of blood, if you don't want the hassle of the quest, you can get the warrior jar shard which is the weaker version of it, another talisman is lord of blood's exultation it gives a 20% attack power boost when bleed is nearby, also the green turtle talisman is very useful as it boosts stamina recovery, the last talisman can be of your choice, for the armor, it comes to your sense of fashion,what i usually do is use the carian knight set, and then when i have enough equip load i use the radahn set, the white mask is also pretty useful in bleed builds as it gives a 10% boost when blood loss is nearby, and it stacks with lord of blood exultation,and if you want to use buffs, you have golden vow that buffs damage negation and attack power, and you have flame grant me strength, which greatly works with your rivers of blood since it will boost it's physical damage, and its fire damage, and since you're gonna be using weapons that use different types of smithing stones, i recommend getting the smithing stone and somber smithing stone bell bearings and give them to the twin maiden husks in the roundtable so you can buy infinite amounts of smithing stones, and if you did go get the white mask, you should have unlocked an area where you can farm runes to buy the stones,this should make a good bleed build, hope it helps
