are there ladder only runewords?

as someone who plays exclusively SP i wondered if there are ladder only runewords anbd is there a list somewhere? ive seen the guides list but no mention of ladder or single player

the only thng ladder only atm is the halloween event

cool lastly where do i find bur and xod and yham havent run across those

They are a very rare drop from a rare enemy in scosglen.

scosglen

iirc bur can also drop from fauzt minibosses (the rest of fauzt stops at ohn), but that's lower odds than just clearing scos

so for me Doing it SP its clear scos... exit restart .. lather rinse repeat figured out early that exit and re start would respawn

look for trees specifically.if you can

everything in scos can drop every rune but the only.mob that actually has buffed rune drop rate is big trees

Or look for luck.
