SRD spells/mage-armor.md: 'An invisible but tangible field of force
surrounds the subject of a mage armor spell, providing a +4 armor bonus
to AC' - 'School conjuration (creation) [force]', level 1, 'Casting Time
1 standard action', 'Range touch', 'Duration 1 hour/level (D)',
'Spell Resistance no'.
- data/spells/mage_armor.json: buff +4 armor to AC, 600 rounds (1
hour/level modeled fixed, the shield.json convention). Description
documents the known simplification: the engine bakes worn armor into
the AC total and cannot see it, so the armor bonus stacks additively
with that baked value (two mage armors still do not stack).
- effects.py: 'armor' added to BonusType; absent from _STACKING_TYPES it
behaves as a keep-the-highest type (verified by resolve_modifiers
tests).
- Spell-count pins 107 -> 108 (test_runner_spells, batch3, test_spells)
and the README references.
- Golden transcript untouched (buff branch only fires when no offensive
spell is selected; the lich still opens with Magic Missile).
Bull's Strength now grants the SRD +4 enhancement bonus to Strength as
+2 melee attack, +2 melee damage and +2 CMB (three modifiers instead of
the previous +1/+1 approximation). Shield now uses a real shield bonus
type (+4 AC) instead of approximating it as deflection: the engine's
BonusType literal and stacking docs gain the shield type, which stays
out of the CMD bonus list (SRD Combat Maneuver Defense). Bear's
Endurance keeps its +2 Fortitude / +2 hp per HD and its description now
cites the SRD and flags the hp modifier as informational. Golden
transcripts updated: the buff log reports 3 mods and Tammara's pistol
attacks gain the extra +1 enhancement (d20=10+9-6=15).
