You may note the counter magic page has been altered, some minor details, mainly that it has been designated a Background, & a 5th level (Spell Tracing) has been added.
Reasoning: I like Backgrounds, & knowledge of Counter-Magic is effectively that: time spent mastering something that is not precisely an ability, just as "Hands of Death" represents time spent driving your hands into buckets of sand or beating on chumps.
What does this mean to all the people who have received/learned Counter-Magic? Congratulations! You have a rating in the new Background of 4, at the measly cost of 12xp. You lot are effectively "Grandfathered in". Newbies getting Counter-Magic will be awarded it at 1.
Spell Layering will be going live as well, as well as Fast Casting & possibly High Ritual. Channeling will be complete as well soon. In short, lots of new toys for the Casters.
