The main area of the ArM magic system I'm dissatisfied with is the heavy limitations with healing and mending magics. Now, as SG, it's prest simplicity to house-rule, but as player, one would have to resort to breakthrough. Since in ArM5, the Lesser Limit of Creation no more includes healing, what kind of Hermetic Breakthrough and modifications to the existing system would be needed to make Healing and Mending spells able to permanently heal without need of Ritual and Vis ?
Some minor checks might be left in place, such as the need to expend fatigue levels, or to concentrate. Wished methods: Creo Animal/Corpus for healing wounds. Creo Animal/Herbam/Terram, to mend objects. Both of these would require expendng fatigue levels (normal, not long-term). Muto Animal/Corpus, for accelerating natural healing rates so that it occurs within minutes. Concentration would need to be maintained as long as accelerated healing takes place.
The Limit of Creation, requiring Vis to create permanent objects and creatures from nothing, would still remain in place. But healing or repairing damage from existing creatures and objects would have permanent effects by default, without need of vis.
It is meant that dying in combat would still be a serious issue, but if you survive it, mages with the appropriate Creo and Muto spells are able to quickly repair damage to themselves, associates, mounts, and equipment. Post-combat crippling and long-term lingering in bed from wounds and diseases become trivial, rare occurrences for covenants folks, and Creo/Corporem vis becomes roughly as precious and sought after as other forms (barring longevity rituals). Healing powers of mages become a significant motivation for mundanes to like the Order of Hermes.
