Rite of Abjuration as is is borderline useless; to say it 'isn't very powerful' is euphemistic to the point of being dishonest. Also, I'm not sure how my suggestion doesn't fit the flavour. I could certainly see reducing the damage on the disenchant, and omitting removal of the other 'emotion' based buffs, but beyond that, the recommendation is spot on.
I could live with making it a minor. Your suggestions for buffing it as a major are far too weak; I'd never use it versus a Gout of Flame/other attack unless the encounter was nothing but casters (with regards to the multiattack version), and even then it would require serious consideration.
As a debuffer, it'd still be trash as a Major. What would 'abjured' terrain spaces be?
Except it's inferior as compared to virtually every other option of its level; Shadow Strike, Twin Strike and Parting Blow (as a prerequisite for the extremely powerful Blade Dance) all are about unarguably superior to it. There is no internal balance between it and competing options.
Further, I'll also note that whatever time pressure niche use it has is even further obviated by flat out superior limited use attacks such as Twin Strike and Blade Dance.
Rite of Abjuration is also worthless given that it costs a Major action and you are virtually always better off attacking with said action instead.
What Vince and Anonymous have said.
We’ve made all the terrain icons a little more opaque to make them stand out more. We’re also looking at giving certain of the dimmer ones brighter colors.
