What’s an easy way to get more runes?

Hello! I’m new to Elden ring. Ive been playing for about a month now and ive managed to reach level 30 and I’ve beat most bosses in limgrave except for maybe 3. But now it’s to the point where I need over 4K runes to upgrade once and on top of dying I haven’t really been getting much 😅 the farming im doing now only gives me maybe 1.1-1.3K at a time. Is it any more farming spots I should know about?

Extra info: I’m a Vagabond, level 30 trying to get Dex, Int & Fai higher (They’re all very low between 8-12). Strength, Endurance and Vigor is all between 18-20.

Should I focus on this or no? Thanks any comments are appreciated:)
