I'm playing in a homebrew Fire Emblem game using a custom sheet. The GM wants to add weather conditions which could affect tokens in different ways depending on their skills. As an example, the weather on a map could be 'Blizzard' which would give tokens with the skill 'Cold Weather Mastery' a +10 hit bonus. The issue comes from the fact that the current weather is a variable not known by the selected/target tokens. Tokens have a skill attribute containing a list of their skills which are read by the script when a token enters combat. Based on the various attributes of the selected/target tokens, said skills may or may not activate. I could implement these new weather skills like the existing skills but it would be a hassle for the GM since they would have to go into each token and remove/add the skill each time the weather changes. Is there a way to create some kind of global variable that the GM could mark as 'Blizzard', 'Sandstorm', 'Sunny', etc? That way the various weather skills could be added with the same format as the other skills and simply not activate if the weather variable is not set to the correct value.
