**Review Needed**
This house rules are taken from an existing saga, with additional
comments about known issues that may need discussion.

# Rule Interpretations

1. Adventure XP is incompatible with any kind of productive work, including
   teaching, writing or copying books, lab work, etc.
   The only exception is mundane work which can be seen as an extension
   of the story.
2. Personal vis source grants 3p/year if a technique, 4p/year if a form.
4. We do not use the optional book rules from [Cov].  This was discussed 
   during the previous saga and considered to be too much bookkeeping.
   **Questioned**
5. It is possible, in the same season,
   to invent some spells using a lab text and 
   others without it. The calculations can be made by using lab text levels as
   a bonus to the lab total, and work out the inventions of all the spells
   as if not using a text.
6. Although ring duration allows permanent effects,
   it should be noted that the ring is fragile.
   In particular, if the ring is obstructed by something
   dropping and covering it, the spell ends.
7. Realm aligned spells to reduce might work on all creatures 
   with might aligned to that realm.
   However more specific versions can be created to benefit from a 
   magical focus.

## Aegis of the Hearth

1.  The Aegis protects the covenant, and it does not extend to 
    the lunar sphere.  Exactly where the magical boundary occurs above
    the covenant will be unpredictable and may vary.
1. Aegis of the Hearth can be invented with different size modifiers,
   even though range/duration/target cannot be modified.
   The base size is 100 paces diameter,
   but +1 (300 paces) versions are common in the Order.

# House rules

1. A magus can fixing several arcane connections in a season, up to
   his Magic Theory score.  However, it is not possible to fix one
   in less than a season, or combine this with other lab activities.
   The fixing process needs to be aligned with celestial cycles, but
   the process allows some parallellism.
3. Fractional xp carry over. In other words, when an odd number of xp is
   assigned to an ability/art with affinity, the half xp should be recorded
   and not rounded up.
   
   *Note*  This can be problematic when several XP/quality modifiers
   apply to the same trait.  Such cases should be checked for future 
   sagas.
4. Untranslated lab texts can be read, and with a Int+Magic Theory roll,
   obtain Technique 6+, Form 6+, Requisites (9+ for 1st, 12+ for 2nd,
   15+ for third etc) and Magnitude (roughly 9+ exactly 12+) and as such 
   4 Magic Theory rolls should be made.
   This whole process takes 1 day per lab text and does not in any way 
   translate the code of the writer.
5. Copying ability books, the copyist needs to accumulate points equal
   to 3 times the level (compared to art books where only points equal
   to the level must be accumulated).

## On Rituals and Botch Dice

1. Rituals are always cast on a stress dice,
   no matter how relaxed the situation. (This is RAW.)
2. Practice of mastery of ritual spells yields 4xp per season.
   It is true that practice by repeatedly casting the spell earns 5xp,
   but this is not practical for rituals, due to the vis cost.
3. A *Safe Casting* mastery option can be learnt, but requires one to
   study a book which explicitly makes it available.
   It halves the number of botch dice, before subtracting the mastery score.
   **QUESTIONED**

*Note* These conditions makes it either risky or expensive to 
go seriously into rituals.  For better or for worse, a ritual specialist
may be unattractive.

# Mythic Europe Interpretations

1. Most magi dress so that they are easily recognisable as members of the Order.
   This often includes badges and insignia, which are known to many 
   learned people.
   Players whose character dresses differently,
   should be careful to state this.
2. The Irish year starts on 1 November (toussaints or Halloween),
   and the year is divided in two, with Summer starting 1 May.
   Matching this with Hermetic seasons, it is reasonable to let the year
   start with Winter 1 November, Spring 1 Februar, Summer 1 May,
   and Autumn 1 August.
   This places solstices and equinoxes approximately mid-season.
   The difficulty is, of course, that the Winter of 1220,
   starts 1 November 1219 by modern calendar.
3. The common calendar year starts with Spring from the Spring Equinox.
   Winter is the last season of the year, from Winter solstice to
   Spring Equinox.

# Necessary house rules

## Regular use spells

Spell use which occurs in session is easy to handle, but daily use 
is susceptible to abuse.

This applies (at least) to

1.  Rego Craft Magic for income and/or cost savings.
2.  Rusticani charged items
3.  Lab Boosting Spells

The Lab Boosting spells are balanced in canon by causing lab warping,
and this seems ok.  It accounts for the risk of mishaps and the distraction
to keep them going.

Rusticani charged items have a definite time requirement, but even so,
an item/hour is commonly achievable.
Using just the ten day distraction allowance,
this gives 80 items/season.
A season of reading, in principle, allows 240 items/season.  
This seems excessively powerful, especially if items are sold.
To date, it has been managed by creating a little more than what seems
sensible, and the effects on the game are minor.

Craft Magic in principle are momentaneous spells.  In theory,
with perfect logistics, the Mystical Carpenter can erect ten houses
per minute.  However, what does it take him to get the materials in
place?  Similarly for Elfin Brewer/Baker, Mystical Blacksmith etc.
In theory, a couple of craft spells could serve as scores of specialists,
saving almost all costs.

+ Main question.  How much time does this take for the magus?
  Most of the time is probably spent organising the grogs for logistics.
  Some may be the disruption of having to cast the spells at
  particular times.
+ Some cap should probably applied to account for the need to acquire and
  check raw materials.  Possibly half the cap of a real craftsman.

# Rejected House Rules

2. Teleportation is not discontinuous disappear/reappear behaviour,
   but rather ultra-fast real movement.
   This means that one cannot teleport out of a complete enclosed room,
   but has in practice no consequences for the 
   speed of movement. An unobstructed path,
   not necessarily a straight line, is required.

   *Note*  We did not really consider the smallest possible opening
   the target can teleport through.  There is also a question of how
   this applies to teleportation in andout of regione.
   This should be reconsidered.
