Excuse me, could you please clarify what you mean by "stacks of runecloth" and "exalted" in this context? Are you referring to a specific game or system where these terms are used? Assuming it's related to a game or a system where reputation or standing is earned through certain actions or items, the answer would greatly depend on the specific mechanics of that game or system. In general, if runecloth is an item that contributes to increasing your reputation or standing within a certain faction or group, and "exalted" is the highest level of reputation you can achieve, the number of Stacks of runecloth required would depend on several factors, such as the base reputation gain per stack, any bonuses or multipliers that may apply, and the current reputation level you're at.

However, it's common for games to have a reputation system that requires players to collect or complete a certain number of tasks or items in order to progress through the different reputation levels.
