Just an FYI, Rober M. et.al., here is an amended macro that uses token-mod's "+n!" syntax in the set command to automatically prevent the bar addition from exceeding the max value for that bar. Avoids having to use the kl1 group roll and just looks a little cleaner. Might save 30ms not having to reference the two other attributes, too. ;) Not sure how long that has been available in token-mod, but I only learned about it recently. /em @{selected|token_name} uses Second Wind and restores hp!
!token-mod {{
--charid @{selected|token_id} --set bar3_value| +[[1d10 + @{selected|base_level}]]!
--report
all|"Amount healed by Second Wind = {bar3_value:abschange}hp."
}}
!ammo @{selected|character_id} class_resource -1 Second Wind
