I'm creating a Herbam specialist for ma saga, and I was wondering if after casting spells that affect the shape of plants or living wood, like "Twist the Living Tree" (ReHe25), those targeted vegetal(s) would retrieve their natural shapes at the end of the spell...
... or if we could consider some durable "remodeling", or bending at least, even after the caster cease to control their shape or movements. Perhaps by adding a +1 magnitude in the design ?
For comparision, I tought on one hand about Rego Terram effects, which would not see displaced stone or bend metals retrieve their initial position or shape, right ? But on the other hand, when you cast some Rego Corpus/Animal on their relevant living targets, these can naturally move and/or regain their initial positions as they like.
But plants are not naturally able of movements, their shapes being more the result of growth, and physicals, external, constraints over their growth, and as such and could be considered as... something in between regarding my Rego dilemma ?

If the form that the plant takes at the end of the spell is one that it could naturally have taken, then the change can persist past the duration of the spell. Thus you can't keep a right-angle bend in a plank of wood, but you can straighten it or warp it with Rego magic, or even weave the branches of a tree together. Personally I wouldn't even impose an additional magnitude, but might require a Finesse roll to determine how much like your desired result you ended up with. Since a metal sword can naturally have a right-angle bend, then that bend can be caused by a momentary duration Rego Terram effect.
Unnatural changes require Muto, and they will always return to a natural state when the spell ends. However, that natural state may not be the same as how they started. A wall turned to watery mud might become a pavement at the end of a Muto Terram spell!
