The character sheet for starfinder thread might be a better place to ask, but here is what I know. If you have the ammo api, which I assume you do, place the below line in the first line of the attacher in any attack on the character sheet. {{buttons0=[Reload?](!ammo @{character_id} repeating_attack_@{id}_ammo [[@{@{character_name}|repeating_attack_@{id}_ammo|max}-@{@{character_name}|repeating_attack_@{id}_ammo}]] @{ammo_type})}} after pasting the first hit enter and past this. This should subtract the amount by what ever is placed the usage field. !wammo @{character_id} repeating_attack_@{id}_ammo [[[[-@{usage}]]*{[[@{full_attack_query}*@{full_attack_number}]]d1,[[1]]d1}kh1]] @{ammo_type}
