When a turn is hosted, all players’ turn orders are resolved simultaneously. The game resolves orders according to the turn order sequence.

• 1) Messages + attachments sent
• 2) Research
• 3) Empowerment
• 4) Recruitment
• 5) Items forged
• 6) Non-heretical preaching (also blood sacrifice?)
• 7) Heretic Preaching (please verify this?)
• 8) Thrones are claimed
• 9) Site entering, pearl cultivation, etc
• 10) Rituals are cast in random order

• 11) Battles caused by rituals, including spells like Teleport and Wind Ride. If a battle ensues in this phase, stealthy units set to attack the province will join. If not, battles involving those units are resolved in the 'main' battle phase
• 12) Battles caused by being on another plane or moving out of one
• 13) Retreating caused by battles in this phase

• 20) Assassination and Seduction attempts
• 21) The Raid order

• 22) Relinquishing (Disciples-games only)

• 23) Movement between friendly provinces.
  • Friendly movement occurs, before movement to enemy provinces, thus allowing defenders to group up.
  • If an intended middle province was taken during the Magic Phase, the armies will not move.
• 24) Movement to unfriendly provinces occurs, including breaking sieges

• 25) Main battle phase.
  • Where movement has lead to opposing armies in the same province, neither hiding, battles occur.
  • Battles are resolved in random order.
  • Provinces may change hands as a result.
• 26) Fort-storming battles. Some retreating enemies from the main battle phase may be inside the fort.
• 27) Retreating caused by battles in this phase

• 28) Global enchantment effects.
• 29) Events occur. These can be random events from luck or misfortune, or caused by players.
  • The spells Wolven Winter and Breath of the Desert cause temperature-changing events which take effect here, not in the ritual phase.
• 30) Event battles, e.g. barbarian attacks, dark vines, Call of the Drugvant, Dark Slumber.
• 31) Retreating caused by battles in this phase

• 32) Reaper, automatic summoning, item/monster enforced scales changes and so on happen here: after events but before income.
• 33) Patrollers units find hiding units.
  • Happens after a Bane Venom Charm has already affected a province.

• 35) Building construction and destruction
• 36) Reanimation and Summon Allies
• 37) Pillaging, which comes after unrest reduction from monsters' inherent properties but before income
• 38) Income, which is before patrolling's unrest reduction, and also before upkeep
• 39) Unrest modification from Dominion, dominion level, scales, and reduction by patrolling
• 40) Starvation
  • calculated after battles etc, so you can walk into a wasteland if your belly's full, once, and not want to run away or get diseased
• 41) Upkeep.
• 42) Dominion spreads
• 43) Dominion effects like innate popkill, insanity, spreading temp or turmoil happen here
• 44) Magic site effects like disease occur now

• 47) Leftover battles occur now
  • what kind of battles can happen here?

• 48) Units heal if able to and are affected by disease here
• 49) If a unit goes insane, this is where it does that
• 50) Mercenary bids are resolved and the troops appear where they have been recruited
• 51) Heroes appear
• 52) Units who have lost their commander are deleted if in enemy territory
• 53) If nothing is sieging a fort, it will take the province back
• 54) Scouting reports are produced
• 55) Defeat conditions are checked
• 56) Victory conditions are checked
• 57) Stat graphs are generated
• 58) Heroic Abilities are updated
• 59) Immortals reform
• 60) Province defense levels are reduced if the population can't support it (10 people/PD point)
• 61) Aftermath (order validation, involuntary shape changing, etc.)

Change in temperature resulting from season changes happens after the battles. Also, surprisingly for example the effect from ritual like Wolven Winter happens only after the battles. This was tested in game (1/2022) and is also confirmed in https://steamcommunity.com/app/722060/discussions/0/3241971691950093989.

As a result, a good rule is: "What you see is what you will fight in on the next turn."
