Task duties
Buffs
Six timers kept topped up — attack, defense, HP, march speed, gathering and production.
The Buffs card carries six independent timers, each its own row: Attack, Defense, HP, March speed, Gathering speed and Resource production. Each one reads what is left on that buff off the game's own window and puts a fresh one up when it runs low.
Which items may be used
The tiers this buff may spend, in the order it should try them — the ordinary one-hour item, the Adv and Super versions, and the longer ones where the game offers them. It spends only what you tick.
Renew before expiry
How long before the countdown ends to put the next one up.
Anchor — ride with a task
Instead of a clock, tie the buff to a task: put the march-speed buff up when Rally Joiner is about to march, or the gathering buff when Resource Gathering sends. An anchored buff waits for its task and says so.
Gems
Whether this buff may ever be bought with gems. Off by default.
An anchored buff resting shows Waiting and names the task it rides with. That is its normal state, not a fault — it is not late, it is waiting for the moment the buff is actually worth spending.
All six reach the game through one shared piece of automation — the City Buff sheet in the keep, which is where every one of these items lives. What to put up, at which tier, and whether gems may be spent stays with the card; the shared part only finds the section and applies the item.
