The descriptions on the following points for Disintegrate don’t match, but they all have the same effect. The mismatched descriptions lead me to believe Inferno acted differently. Please change the Inferno talent to behave as described, or fix the description.
Galvanized Defense - “while channeling Disintegrate”
Praesidium - “while channeling Disintegrate”
Lucomancer - “While channeling Disintegrate”
Inferno - “while channeling”
I confirmed the interaction by putting points into Inferno and channeling Focus. I did not gain the Inferno effect.
