Most of the hard cover books have a sentence similar to this one:
All material from this book is legal for play except as noted below. Some rules elements are legal but function differently in Pathfinder Society Organized Play, as described.
The entry for Ultimate Magic entry does not have a similar sentence opening most of the book up to play. I assume this was an oversight because the entry is mostly written with specific things that are not authorized.
As an example nothing specifically authorized the Magus class for play. Also nothing opens up any Archtypes, Feats, Equipment, or discoveries.
Am I missing something here, is there a general assumption that everything in a hard cover is legal unless otherwise specified?
Anyone playing the magus playtest version must have updated his or her character as of 5/19/11. The following are NOT legal for play:
Alternate class abilities: alchemical simulacrum discovery, alchemical zombie discovery, doppelganger simulacrum discovery, and greater alchemical simulacrum discovery are not legal for play.
Archetypes: broodmaster summoner, clone master alchemist, gravewalker witch, pack lord druid, master summoner, reincarnated druid, sanguine wildblooded, synthesist summoner, undead lord cleric, vivisectionist alchemist archetypes are not legal for play.
Discoveries: arcane builder arcane discovery, golem constructor arcane discovery, true name arcane discovery, staff-like wand arcane discovery are not legal for play.
Feats: Blighted Critical, Create Reliquary Arms and Shield, Create Sanguine Elixir are not legal for play.
Hexes: child scent hex, poison steep hex, cook people major hex, and witch's brew major hex are not legal for play.
The following function differently than written in the sourcebook:
Bottled ooze discovery may only be used to bottle oozes which appear in the Pathfinder RPG Bestiary.
Geisha bard archetype grants Spell Focus instead of Scribe Scroll.
Clerics using alternate channeling rules who worship a deity not listed in the Core Rulebook must provide a copy of the source in which their god's portfolio is listed.
Clostered Cleric archetype grants Spell Focus at 4th level in place of Scribe Scroll.
An ex-Inquisitor may not replace existing class abilities with those granted by the Heretic inquisitor.
A broken monk vow only requires a casting of atonement to be renewed.
The Time oracle mystery grants hold monster at 10th level in place of permanency.
Evolutionist summoners may only mutate an eidolon between sessions.
Familiars: all familiars in Chapter 2 and all improved familiars on page 251 are legal;
Spells: all spells are legal for play except blood transcription and those which grant a spellblight (such as curse of magic negation or steal voice);
Other: No content from Chapter 2 is legal for play except new familiars; Words of Power are also forbidden.
That is certainly my assumption, but it really should have a similar line.
