Any channeler who learned to channel on their own (i.e. what the Aes Sedai call a Wilder) may have developed some ``crutches'' that helped them to understand their power. Most common is the belief that some particular condition must be met in order to channel. Aes Sedai call this a ``block''. There are modifiers to how much a block is worth, but the base is -5 points.
Frequency:
The condition must always be met: -5
Condition must be met on 15 or less: -3
Condition must be met on 9 or less: -0
Rarity of condition:
Common (anger, water, gestures, gold rings): +5
Uncommon (particular weather, a certain person): +0
Rare (a particular ring, someone is dying): -5
Completely random / no condition (see frequency): +0
Extent of block:
Cannot even sense the One Power or its use: -5
The Enemy disadvantage [insert page reference] is fairly common in WoT. Certainly any man who can channel is likely to have either the Secret disadvantage [page reference] or have Aes Sedai as an Enemy. How frequent the Aes Sedai will appear should be discussed with your GM, but will likely depend on how well they know of you. The Red Ajah is very focused on finding men who can channel, so it would not be surprising to have any use of the Power communicated back to them.
If an Ogier has been away from a stedding for over two years, or has spent less than half of that time in a stedding, he or she will begin to to feel a certain pronounced homesickness. Thereafter, every month they must make a HT check, or lose 1 HT, permanently. They must also make a Will check every six months, or drop what they are doing and head directly to the nearest stedding.
A person who has been cut off from the Source will always feel the enormity of that loss. Most people who have been Stilled or gentled will eventually (sometimes immediately) commit suicide. Those who do not must find something in their lives to make up for the gaping hole left by the loss of the Source. For some this is revenge against those who did this to them. For some it is a pursuit which engages them completely. Whatever it is, it must border on an obsession in order to be enough. Simply working hard will not be enough.
Anyone who has been Stilled will not want to talk about it. If the issue is forced, they may become violent or run away. Make a Will roll if the issue is pressed, in order to remain calm. They will also be prone to dark and melancholy moods.
All men who can channel are subject to the Taint. This is only taken as a disadvantage, if the character can actually channel (e.g. has the Magery advantage).
