The Four Condition Kinds
Every condition in the game is one of four kinds, and the writ editor colors each kind so a rule can be read at a glance. Two kinds decide whether a rule fires; two decide whom it strikes first. Learn the four colors and you can read any writ in the Reach.
Filter — narrow the targets
A Filter asks a question of every candidate target and keeps only those that answer yes. Narrows the targets the rule may reach; the rule is skipped if none are left.
Examples: HP Below 50% Back Row Not Targeted By Ally Target Is Cleric
Heal Light + HP Below 50% fires only when someone is actually below half — and never over-mends a healthy squad.
Gate — ask about yourself
A Gate asks one yes-or-no question about the acting soldier or the field, not about any target. A no skips the rule outright.
Examples: Own HP Below 25% Own AP 2 Or More First Action Own Squad HP Below 50%
Gates write personality: a soldier who fights differently when hurt, opens every battle with a war-cry, or saves their last AP for the retreat.
Prefer — favor, but settle
A Prefer asks the same kind of question a Filter does — but sorts the targets instead of pruning them. Ones that match are struck first; the rest stay eligible. A Prefer can never empty a rule's targets, so it can never stop a rule from firing.
Examples: Prioritize Wounded Prioritize Back Row Prioritize Untargeted Prioritize Focus Fire
The difference is the whole point: Back Row (filter) skips the rule when every enemy is up front; Prioritize Back Row (prefer) shoots the front line instead. One is a requirement, the other a taste.
Prioritize — rank by a measure
A Prioritize ranks the targets by a measure — highest or lowest of something — and the rule strikes the top of the ranking.
Examples: Lowest HP Highest Magic Defense Highest Initiative Lowest Evasion
How they compose
Within one rule, the conditions work in a fixed frame:
- Filters and Gates decide whether a rule fires. Under And each filter narrows what the next one sees; under Or any one match is enough, and one passing gate carries the rule alone.
- Prefers and Prioritizes decide whom it strikes first — in the order you listed them. The first sorts the targets; each later one breaks the ties the one before it left.
- The weakest takes what remains. After all your stated preferences, any final tie goes to the target with the least health.
So a rule reading Sniper Shot · Back Row · Lowest HP means: only if someone hides in the back rank; among them, the nearest to falling. Every writ in the game is just stacks of that sentence-shape, in the order you chose. The full catalog of conditions — all of them, by drawer — is in the condition reference.
