A topic from AEG's L5R CCG Rules forum, copied for Oracle of the Void from a copy of the forum saved in October 2015, so pages it didn't save are missing. Players' names are left out; the rules officials are named. Rulings are as they stood on these dates; later rulings, the rulebooks and the Rules Archive may differ.

0) While I think I understand why the text of Mark of Heaven's Favor specifies "positive numeral", I am unsure about what that means. I would understand "positive integer" or "positive number" but it would appear a "numeral" can not be positive or negative. "-5" is not a numeral, for example, but it is written using the numeral "5".
1) In the context of L5R rules, is "0" a positive or negative numeral?
2) What happens if Mark of Heaven's Favor is used to increase one of the instances of "4" appearing on the Obsidian Dojo (20F)? Will the Fear 5 affect only targets with 4F or less, or will the Fear 4 affect targets with 5F or less?
2bis) What happens if Mark of Heaven's Favor is used to increase an instance of "2" appearing in the description of the Kharmic ability appearing on, say, Voice of Experience (TCS)? Is the GC increase to 3 affecting both players or only the owner of the Marked Holding?

0. On L5R cards, "numeral" is used as a shorthand for "number written with numerals".
1. 0 is neither positive nor negative.
2. There is only one 4 on Obsidian Dojo that can be affected by Mark of Heaven's Favor. Reminder text does not affect play.
2b. As above, numbers in reminder text are not affected by Mark of Heaven's Favor.
