Field Manual

Everything in Last Days: Zombie Apocalypse and Seasons the tracker uses. Stats and costs are as printed; rules are summarised with page numbers (LD = core rulebook, S = Seasons).

Conditions (S p.12)

Hunger	Hungry: Can't Run; Heavy items count one level higher.	Starving: Can't go on missions; counts as a casualty for Zombie Attacks.
Health	Sick: After a mission, others not Sick catch it on a 1; then each Sick character is Bedridden on 1-2.	Bedridden: Can't go on missions; counts as a casualty until treated.
Thirst	Thirsty: -1 Intelligence. Running: on a 1 lose remaining AP and halve CQC this turn.	Dehydrated: Can't go on missions; counts as a casualty for Zombie Attacks.
Warmth	Cold: -1 Endurance on missions. Each Job fails on a 1 (resources refunded).	Freezing: Can't go on missions; counts as a casualty for Zombie Attacks.

Two Conditions at Critical and the character dies. Spring and Fall manage Hunger and Health; Summer adds Thirst; Winter adds Cold. In March and November a 1 on a D6 adds Cold; in May and September a 1 adds Thirst.

How this tracker reads the books

Group Level Balancing's first row is printed "5–0"; the tracker reads it as a difference of 6–10 (+1 XP), as the next row starts at 11.
Seasons gear and vehicles carry no ‘*’, so under a Professional they go to the stash; vehicles may still be bought as Rare Equipment.
Neutral and off-keyword limits are counted against the whole group, leader included, rounding down.
Starting skills count towards the three a character needs before rolling on a Master Skill table.
Spring and Fall weather tables are identical apart from roll 12.
Chaos Theory: when the Seasons Farm House is rolled, its choice of Fenced-Off Garden or Stable is rolled too, and survivors who pick skill types have them rolled.
Chaos Theory: without the Seasons rules, Seasons-only refuges and survivors are re-rolled, and a Horse becomes a Dog.
