In the rating system of the Modern Tecton, a general class donor. The general class donor does not give personal transfer and does not feel selyn movement when the channel is taking down his/her field.

Could not reduce their field to "the comfort range," not causing any sensation to the donor. Selyn gained could support a renSime for nearly a month. Channel's method of collecting this selyn is not as wasteful as the Kill.
