Shatter, Fester, Shield break: the three reactions in Ringfort
Why we gave a 122-item auto-battler only three combo rules, and what each one asks you to build
Ringfort has 122 items, race bonds, cross-race styles, enchantments and talents. With that many moving parts, the easy move would have been to add a special interaction for every pair of effects. We went the other way. The whole game has exactly three reactions, they apply to every fort, and every one of them fits in a single sentence.
This note is about those three rules, how they work, and why we kept the list so short.
Why only three
In Ringfort, six forts sit on a ring and every fort fights both of its neighbours at once, every round. A lot happens on screen. If a combo rule needs a paragraph to explain, nobody can see it happen in the middle of that brawl, and a rule you cannot see is a rule you cannot plan around.
So we set a simple bar: a reaction has to be one sentence, it has to come from effects players already use, and it has to show up as a word on screen when it fires. Three rules passed.
Shatter
While any of an enemy fort’s items is frozen, your direct damage to that fort is multiplied by 1.3.
Freeze in Ringfort does not stop an item. It slows its cooldown to a quarter speed. Repeat freezes on the same item get shorter, and an item that has just thawed cannot be frozen again for 1.5 seconds. That means you cannot lock a fort down forever, but a steady trickle of frost keeps at least one enemy item cold most of the time, and that is all Shatter needs.
The build it suggests is control in front, heavy hitters behind: frost to open the window, weapons to cash it in.
Fester
While a fort is also burning, every poison tick on it is multiplied by 1.5.

Burn and poison already play differently. Burn deals its stacks every half second and loses a stack each tick, and it ignores shields. Poison costs walls every second per stack, never wears off during the fight, carries a third of itself into the next round, and halves repairs. Fester is what happens when you stop picking one and run both: the fire keeps the poison ticking harder for as long as the fire lasts.
A small story from development: this reaction was first called Blight in English. The Undead race rule was also called Blight, so the same word meant two different things in two different tooltips. We renamed the reaction to Fester, which also says what it does a little better.
Shield break
Knock out a shield of 30 or more in a single hit, and that fort takes 1.25 times direct damage for the next 2 seconds.
Shields in Ringfort absorb damage before your walls take it and can stack up to half your max walls, so shield-heavy forts are a real wall to chew through. Shield break rewards the moment you finally get through. Small chip damage that whittles a shield down to nothing over time does not count; it has to be a hit big enough to take out a shield of 30 or more in one go.
The build it suggests is a few big, slow hits instead of many small fast ones, or a piercing threat that makes the opponent lean on shields in the first place.
Seeing them happen
Each reaction shows up as its own word next to the fort when it fires, in a column outside the castle so it never covers the wall bar. After the fight, the summary tells you how many Shatter hits you landed and how many times Fester ticked.
They also have their own Steam Achievements: Shatter for landing 20 Shatter hits in one fight, Festering Flame for triggering Fester 20 times in one fight, and Shieldbreaker for breaking shields 3 times in one fight.
