What are examples of the 7 buff buildings to make combat easy rather than the Fire Phoenix?
When the AI units are favorable, I like to use a combo of archers & golems - both have good range and can sweep the field. The mix varies according to the AI - archers for mages & heavy infantry, golems for all light units. Against heavy ranged, I have to shift out.
If everyone else is talking about the same thing I'm thinking of, I know of only four of them:
Unleashed Unit Upgrade - 2x2 5-day expiring building. +25% troop health. Found in MA crafts.
Magnificent Mage Multiplier - 2x2 5-day expiring building. +50% mage damage. Found in MA crafts.
Enlightened Light Range - 2x2 5-day expiring building. +50% light range damage. Found in MA crafts.
Dwarven Armorer - 2x3 5-day expiring building. +50% troop health. Found as a possible prize in various Spire chests.
There were a couple other similarly-expiring buildings that I heard were sold in some kind of promotional.
Either way,
all these buildings stack with each other, so if you wanted to transform all your light ranged troops into miniature Death Stars, go ahead and flood the entire town with ELR.
The wisdom of burning that many expiring buildings when your supply can't cope is a whole 'nother kettle of fish. But at least for that 5 day stretch, it'll be as if a second sun rose above your city to smite all who come against it
There are also Ancient Wonders that also provide a damage boost to various troop types, but the expiring buildings above are available (
very relatively speaking) right from the git-go.
EDIT: On a re-read of the thread, perhaps it was meant that "7 buff buildings" was less "types" and more "actual buildings" altogether. The previous spire/tourney cycle, I burned 5 buff buildings: 4 MMM and 1 DA.
