Saga in Stone

A hundred runestones sounds wholesome until you learn the Raise Runestone decision has a ten-year cooldown - the wiki's own verdict is that normal play would take about a thousand years, so don't. The documented fast route is a cooldown-reset exploit: build a custom Norse ruler replacing the 1066 Seljuk emperor (46, unmarried, one son, max Stewardship), bank ~6,000 gold, land your son, then deliberately cycle your rank - provoke deposition factions with failed imprisonments and surrender - because the decision refreshes on rank change rather than the timer. Each stone costs a minimum of 50 gold; any dynasty member's raises count towards the hundred. Ugly, effective, wiki-endorsed.
