Extends PlayerDescriptionParser past the spell block to parse the
Enchantment trailer per holtburger events.rs:462-501 +
magic/types.rs:40. New EnchantmentEntry record carries the full
60-64 byte wire payload:
u16 spell_id, layer, spell_category, has_spell_set_id
u32 power_level
f64 start_time, duration
u32 caster_guid
f32 degrade_modifier, degrade_limit
f64 last_time_degraded
u32 stat_mod_type, stat_mod_key
f32 stat_mod_value
[u32 spell_set_id]?
+ EnchantmentBucket (Multiplicative / Additive / Cooldown / Vitae)
EnchantmentMask outer u32 selects which buckets follow; each bucket
(except Vitae) is u32 count + N records. Vitae is a singleton.
Parsed.Enchantments now exposed as IReadOnlyList<EnchantmentEntry>.
GameEventWiring routes each entry through Spellbook.OnEnchantmentAdded
with the full StatMod data + bucket. EnchantmentMath.GetMod consumes
StatMod records to produce real (Multiplier, Additive) per stat key:
Bucket 1 (Multiplicative): multiplier *= val
Bucket 2 (Additive): additive += val
Bucket 8 (Vitae): multiplier *= val (applied last)
Bucket 4 (Cooldown): skipped (not a vital mod)
ActiveEnchantmentRecord extended with optional StatModType /
StatModKey / StatModValue / Bucket fields. Existing 4-arg callers
stay compatible (defaults to null / 0). New OnEnchantmentAdded
overload accepts the full record from PlayerDescription path.
Tests: 7 new (834 -> 841):
- PlayerDescriptionParserTests (2): enchantment block schema with
multiplicative + additive buckets, Vitae singleton.
- EnchantmentMathTests (5): multiplicative buffs aggregate, additive
buffs sum, stat-key mismatch filters out, Vitae applied
multiplicatively, family-stacking picks higher spell-id.
Closes#7 (parser past spells, enchantment block parsed).
Closes#12 (StatMod flow architecture — data lights up #6's
aggregator). Files #13 (remaining trailer sections: options /
shortcuts / hotbars / desired_comps / spellbook_filters / options2 /
gameplay_options / inventory / equipped — needs the heuristic
gameplay_options walker per holtburger).
Note: ParseMagicUpdateEnchantment (live-update 0x02C2) NOT yet
extended — still uses 4-field summary. PlayerDescription is the
load-bearing path for #6; live updates can be folded in separately.
