make a +200% buff 18h (24 on friends) for iron mines :D

Your math is wrong, should be 16h if 24h (placed by friend) is what you're aiming for.

So many +200% buffs available already, why invent a new one?

If placed by a player with Premium you won't have a buff lasting 24h anyway.

i get the impression u are asking for something very specific to u. i dont see this meeting the requirements of most players as there are plenty of buffs to choose from already.

just have alot of gold fevers i dont use, and think it would be nice to have iron version of that buff

Use red flying settler buff? 24 hour long, +200%

It's not exactly what you are asking for, but there is a buff called 'Golden Ribbon' that can be used on Iron Mines and Smelters that can be made using collectibles in the Mayor's House and buffs +200% for 12/18/19.8 hours (self/friend/premium).
