Each day is divided up into a series of Turns, and each Side gets a single Turn per day.
A Turn is a period of time, in which certain actions may be taken by a Side. It is not the same thing as Dawn, the beginning of the Day, although the first side to have a turn starts at Dawn. Sides, whose turn comes later, have to wait for it. All units of the side naturally realize, when their side's turn starts.
The natural turn order is determined by the age of the side.Erf-b3-p150
For a given side, if it doesn't share a battlespace and will not share potential battlespaces in the upcoming turn with a certain another side's units, then that another side's turn is skipped for them. Battlespace determinations are Natural Predictamancy.Erf-b0-p27
If multiple Sides ally, they take turns simultaneously, on the Turn of the last ally. For instance, in example of three sides A, B and C that naturally take turn in order, if Side A allies with Side C, then Side B will take Turn before Sides A and C, who take Turn simultaneously. If Sides A and B ally, they will both still take Turn before Side C, but they will do so simultaneously instead of consecutively. It's not clear how turns resolve when the alliances break.
So, a side starts the turn of Dawn if it's the oldest side in Erfworld, or if all the older sides in the vicinity either could not have a potential battle with it or are allied with at least one newer side.
Rough order of turns based on the events of the comic is:
Note: The individual sides in the Coalition may normally take their turns in a different order.
Acting on Turn
At the beginning of Turn:
- All Units healErf-b1-p046a and are cleansed. Any damage to their raiment is repaired.LIAB Prologue 4
- Rations pop.Erf-b1-p037 and Erf-b1-p106
- Corpses of the Side coming on Turn disappear.Erf-b1-p077a
- Critically Incapacitated Units croak.
During its Turn, a Unit may:
Ending a Turn
Once a Side has completed all of the actions it wishes to perform for all the Units on its Side, the ruler or the Chief Warlord declares the Side's Turn is over. The day proceeds to the next Side's Turn.
Acting on Another Side's Turn
- Defend itself from attack
- Attack enemies only when enemies are in its hex.
- Cast Spells only when enemies are in its hex.
- Automatically attack when in contact with non-allied units, unless a commander is present.
- Use Natural Abilities.
- Change position within its hex (e.g. Lord Hamster's many redeployments during the Battle for Gobwin Knob)
Turnamancy may affect the Turn in some way. It has been noted that it can, in fact, be used to end an opposing side's turn prematurely, even if only in a caster link. What other uses it may have in this respect are unclear.
A turn ends on its own possibly through the innate magic of Natural Turnamancy.
It is unknown how turning to another side impacts the start of turn stat recovery. It may be possible for two sides that are close friends, but not allied in the mechanical sense of an alliance, to have all field units switch sides just before the other side's turn starts and recover stats multiple times in a single day. It might even be possible to replicate such an effect artificially on a single side with a Dittomancy Turnamancy caster link.
