Proposed Canon
A Veil is an effect that makes units or cities less detectable by enemy.
A veil can be created by a magic SpellErf-b1-p064 cast by a Foolamancer on a Unit or cityErf-b1-p107. The Unit is given the appearance of something else; in the case of trying to hide, something innocuous is usually best. (E.g. a city may appear to be a forest.) It is not possible to make something completely invisible: the size of the veil is proportional to the size of the original unitErf-b1-p115: it is easier to veil a human than a dwagon. In at least one case, a Sound Effect of DE-SPOOF accompanied the process of un-veiling. TBFGK_86:5
Limitations of the Spell:
- In order to be able to Veil units Foolamancer must be in the stack that is being veiled.Erf-b1-p064
- The spell cannot be cast on the enemy's Turn, like all spells.Erf-b1-p064
- Foolamancer must not be linked with other casters. 'we can't do it with the Eyemancers linked up' Erf-b1-p064
- When veiling cities, only one city can be veiled at a time.Erf-b1-p107 (This is likely due to the requirement that the Foolamancer be in the city to be veiled, but may be due to the Juice cost of the spell.)
Enemy Warlords may be able to pierce a Veil if they are present in the same hex and observing the Veiled Units, but they must notice something odd about the Units.Erf-b1-p115 The more Units that are in a veiled stack and the more enemy warlords are in the hex the higher are chances of blowing the veil.Erf-b1-p107
Some veils are more difficult than others; hiding in trees is easier than hiding in the open air, with the sun making shadows. Maintaining a veil over a long period can take more juice.
Spotting units get one spot check during the veiled units' turn, and a new spot check at the beginning of their own turn.
Practitioners of Foolamancy (Foolamancers and Archons) can see through other units' veils.
Scouts have a better than average chance to spot veiled troops; this chance increases with level.
A scouting veil is an item (likely a Magic Item) worn as a piece of clothing that creates the same effect. These are fragile items and are easily destroyed.
It is not clear whether regular Units have less chances to blow a Veil or whether they can blow a Veil at all.
