Here's where I am currently:
Wyrds
Wyrd is a catch-all term for the many different Psykers who inhabit the galaxy. Some are untrained, unsanctioned Psykers who have been overlooked by the Black Ships and are generally unaware of their true talents or have very limited control of their powers, whereas more powerful Wyrds have great control over a far greater array of powers. All Wyrds, however powerful, shine brightly as a beacon in the warp and as such are at great risk from attack by warp entities whenever they use their powers.
A fighter who has the option of becoming a Wyrd will be shown in the individual warband list. All Wyrds follow the same rules unless otherwise stated in their particular warband entry.
Unless otherwise stated, a fighter may only become a Wyrd at creation. The cost becoming a Wyrd depends on their chosen Wyrd Level:
Wyrd Level 1: +30TG
Wyrd Level 2: +55TG
Wyrd Level 3: +80TG
Psychic Powers: A Wyrd has a number of Major and Minor Powers equal to their Wyrd Level. These powers are determined randomly upon creation by rolling on the relevant Power Tables. Re-roll any duplicate powers.
Minor powers are rolled randomly on the Minor Powers table.
Major Powers are rolled randomly on any ONE Major Power table available to the Wyrd. Unless stated in a Warband List, a Wyrd has access to any Major Powers Table.
Psychic Study: Whenever a Wyrd gains a level, after rolling for his advancement as normal, he may choose to attempt to learn a new power. As a Wyrd only has a limited capacity for learning the intricacies of each power, if he already has a number of Major and Minor powers equal to or higher than his Wyrd Level, in order to learn a new power in this manner he must "forget" one of his current powers. Choose which power the Wyrd will "forget" if required and immediately roll a new power of the same type (i.e. Major or Minor) available to the Wyrd. A Wyrd who has less Major or Minor powers than his current Wyrd level does not have to "forget" a power to learn a new one.
When a Wyrd gains a level and rolls a 12 on his advancement roll, rather than choosing a skill from any skill table, he may instead choose to gain a Wyrd Level (to a maximum of Level 3). Note that the Wyrd does not gain additional powers as part of this Wyrd Level increase and must learn new powers as above. If the Wyrd is already Level 3, he may instead choose to learn a new minor power (roll for this as normal, re-rolling results of "no minor power") as above but without having to forget a current power.
Suffer Not The Witch To Live: Wyrds may never be taken in the following warbands: Ecclesiarchal Delegations, Puritan Imperial warbands, Expurgator Squads.
Manifesting Powers: In order to manifest a psychic power, the Wyrd must perform a Psychic Test. See OCE rulebook for details of performing Psychic Tests.
A Wyrd may manifest a number of Psychic Powers per turn equal to his Wyrd Level. Note that some powers state "instead of shooting" or "instead of moving". A Wyrd may only sacrifice each phase in this way once per turn. Also, some powers are "always active" and as such no attempt to manifest is required so they do not count towards the total number of powers a Wyrd may attempt per turn.
Psychic Fatigue: If a Wyrd attempts to manifest a Major Power and fails the Psychic test, he becomes fatigued and may not attempt to manifest any more powers this turn. Also any powers whose effects remain in play immediately end. Powers which are "always active" are unaffected.
Perils of the Warp: See OCE rulebook for details with the following modifications:
A higher level Wyrd learns to protect himself from un-necessary exposure to the Warp and how to fend off attacks from Warp entities. As such, a Wyrd gains the following modifications to the Perils of the Warp rules depending on his level:
Level 1 - No change
Level 2 - Wyrd only suffers Perils of the Warp when attempting to manifest Major powers.
Level 3 - As Level 2. May re-roll result on Perils of the Warp chart but must accept the new result even if it is worse.
=====================================
That's it so far. Let me know your thoughts. Powers will be as OCE for time being, maybe with slight mods to suit the setting but mostly as-is. Working on Beastmaster powers next as they need most work for multi level wyrds.
