Mathilde once grabbed a miscast out of our Shyish ducking's head and it curdled into dhar in Mathilde's hand and was immediately burnt by the belt, though the miscast might have been going to result in dhar regardless.
Anyway, the votes do not say anything about Mathilde doing something that results in dhar, so I am going to assume that is not going to happen.
I think it was implied that the miscast was already curdling Shysh into Dhar yeah. The most clear cut example of Mathilde making Dhar was the exposure of AV to Morslieb and her experiments into Tongs. Both of them had a reasonable expectation of making Dhar and that is what they made.
