No, runes dont stack. It's actually impossible to put the same one on the same item twice.
For the umpteenth time –
So I’ll ask this for hopefully the first time:
I’ve been PWOTiming with DF for about a year now, MW mod for the past eight months or so. I’ve worked my way through the 740+ pages of MW discussion and most of the vanilla Wiki. Both the hardcode core and the mod are continually updating but most of the major kinks seem to have been worked out.
If I had one wish, a freebie, it would be that the SMF search engine was better. Or that I was better at understanding how to use it, either way works.
Is this a common thing? Most questions (newbie and non-newbie) seem to be asked more than once, answered more than once and yet it isn’t often easy to find answers with a keyword search or an “advanced” search on the Bay12 forum. Whyizzat? Would it help if an answer were tagged, KEYWORD: [whatever] ? … using keyword/colon combo as a searchable item? Granted, sometimes it isn’t all that hard to find the answer to a question with the current SMF engine but mostly, it is.
[and if this question has already been asked and answered, feel free to point out the irony of ignorance but then maybe add which search terms would have pointed that out – and thanks]
