Seraphism is an unnecessary skill on scholar that thematically clashes. Miasma 2 is a skill strongly associated with scholar. Sage is a new job without a coherent identity.

While I'm here, could you also add ruin 2 to the tactician mastery trait? It seems to have been overlooked in the media tour tooltips.
