## Summary
Profiling with thousands of creatures in range of each other showed `BaseAI.IsInvalidFactionTarget` checking Ethereal Voyage and active Honor on every acquisition candidate and then calling `BaseCreature.IsEnemy`, which checked both again. This makes `IsEnemy` the single authority and removes the duplicate per-pair work.
## Changes
- **`BaseCreature.IsEnemy`**: the Ethereal Voyage check sat below the `m is not BaseCreature` early return, so it never reached players — the only mobiles that cast it. It is hoisted next to the Honor veto. `GetMaster()` was called three times per creature pair (inside `Ethics.Player.Find(m, true)` and twice at the bottom); it is now computed once.
- **`BaseAI.IsInvalidFactionTarget`**: reduced to `IsFriend` / `IsEnemy` / `CanBeHarmful`. The removed `Combatant != m` Honor exception was dead code — `IsEnemy` vetoed Honor unconditionally on the following line.
- **`Ethics.Player.Find`** / **`TransformationSpellHelper.GetContext`**: small simplifications on the same path.
## Behavior
- `ShouldAcquireOnApproach` and `OnAggressiveAction` only consult `IsEnemy`, so movement-triggered acquisition now respects Ethereal Voyage for players (previously a player under Ethereal Voyage walking past a monster was still acquired on approach).
- `BaseFactionGuard.IsEnemy` does not call base, so faction guards no longer skip honoring/voyaging enemy-faction players. Accepted: both mechanics describe monsters, not guards.
- `HealerAI`/`BerserkAI`/`PredatorAI` (`bFacFriend`) callers are unaffected — `IsFriend` already required a `BaseCreature`, so players were excluded before these checks ran. `MilitiaFighter`/`MilitiaCanoneer` return `false` for all players, so they are unaffected too.
## Testing
- `dotnet build` clean.
- Pure predicate reorder; no new tests.
## Summary
Implements T2A-accurate mechanics for the three defensive spells based on UO98 demo scripts. Pre-UOR (`!Core.UOR`) triggers the new behavior; UOR and AOS paths are unchanged.
- **Reactive Armor**: percentage-based melee damage reflection (10-35% based on target Magery), targeted, timed (25-75s). Guards exempt, ranged attacks beyond 1 tile unaffected. Reflected damage is sourceless.
- **Protection**: temporary AC bonus (casterMagery/10, 1-10 AR) via VirtualArmorMod, targeted, timed (12-120s). Shared table with Arch Protection — only one protection buff per mobile.
- **Magic Reflect**: single-use spell reflection using MagicDamageAbsorb as a flag. No timer, no DefensiveSpell lock. Consumed on first reflected spell.
- **Arch Protection**: T2A path applies Protection via shared table with area sound (0x1F7 vs 0x1ED).
- No DefensiveSpell mutual exclusion for T2A — all three spells operate independently.
## Test plan
- [x] Set expansion to T2A
- [x] Cast Reactive Armor on self → verify particles (0x376A) and sound (0x1F2)
- [x] Get hit in melee → verify attacker takes reflected damage with spark effect and sound
- [x] Get hit by ranged weapon from > 1 tile → verify no reflection
- [x] Wait for RA to expire → verify effect ends silently
- [x] Cast RA on target that already has it → verify "This spell is already in effect"
- [x] Cast Protection on another player → verify particles (0x375A) and sound (0x1ED)
- [x] Check target's AR → verify it increased by casterMagery/10
- [x] Wait for Protection to expire → verify AR returns to normal
- [x] Cast Protection on self, then cast Protection on another player → verify both succeed
- [x] Cast Arch Protection on ground near allies → verify each gets AR bonus with sound 0x1F7
- [x] Cast Arch Protection near a target already protected → verify that target is skipped
- [x] Cast Magic Reflect on self → verify particles (0x375A) and sound (0x1E9)
- [x] Have an enemy cast a harmful spell at you → verify spell reflects back, effect consumed
- [x] Cast Magic Reflect again → verify it can be recast after consumption
- [x] Cast Magic Reflect when already active → verify "This spell is already in effect"
- [x] Verify all three spells can be active simultaneously on the same mobile
- [x] Switch expansion to UOR → verify existing UOR behavior unchanged
- [x] Switch expansion to AOS → verify existing AOS behavior unchanged
## Summary
- Adds `public virtual bool Murderer => Kills >= 5` property to `Mobile`, replacing ~30 scattered `Kills >= 5` / `Kills < 5` magic-number checks across the codebase
- `BaseCreature` overrides `Murderer` to also return `true` when `AlwaysMurderer` is set
- Updates `Corpse` serialization to v15, storing `_murderer` as a `bool` field (migrated from `int Kills >= 5` in earlier versions)
### Summary
- Fixes various memory leaks related to spells
- Fixes Spell Plague
- Added ability to determine if `sdi` should take effect for Spell Damage.
- Fixes animal form timer ticking non-stop while logged out.
### Summary
TLDR - .NET Framework rounded TimeSpan (and some DateTime) methods to the nearest millisecond. This was actually _expected_ accidentally for parts of RunUO.
We are aiming to fix this and clean up some other bad assumptions.
Closes#1604
### Summary
Eliminates `IPooledEnumerable<BaseMulti>` and `eable.Free()` from `Map` for multis. This drastically simplifies code that iterates in range, for example:
```cs
foreach (var m in m.GetMultisInRange(5))
{
}
```
The code above no longer requires an eable and calling `Free()`.
### Bug Fixes
- [X] Fixes an issue with searching through nested empty containers.
- [X] `BaseRegion.CheckTravel` now properly cascades through parent regions
- [X] `SpellHelper.CheckTravel` now returns a failure message instead of sending one internally.
- [X] Consolidates travel restriction messages so they aren't duplicated.

- [X] Fixes field spells so they aren't unnecessarily using a Point3D ref more than necessary.
- [X] Removes extra allocation in campfire by using reverse loop.
- [X] Removes other LINQ calls that aren't needed.
- [X] Caches DateTime.NowUtc on the game loop (not other threads)
- [X] Replaces all locations where it makes sense

Closes#261
- [X] Fixes map issues at New Haven by turning off static diffs
- [X] Some code cleanup and reformatting of tile matrix, tile matrix patch, and tile data
- [X] Adds NetState.Flush for generating spawners so it doesn't feel like the server is frozen
- [X] Reverts NativeReader changes from a while back.
- [X] Adds more string reading for BufferReader.
Notes:
BufferReader is still `little endian` compared to `SpanReader` which is `big endian` (for packets). To that end, the RunUO deserialization `ReadString()` was made obsolete since it is ambiguous, and contains extra fields other than simply reading a string. Furthermore, we shouldn't be using UTF8 (for now) since it is slow.
- [X] Fixes several bugs
- [X] Updates more ordinal issues
- [X] Cleans up the code a bit
- [X] Turns classes static that should have been
- [X] Changes TcpServer.Instances to a HashSet
Bumps release version
