Idea for new battle magic: some kind of acid shadow fog that rolls across the ground and sticks/sinks in holes and low areas. Obscures vision and blots out light. Something like dnd Cloudkill.
Perhaps some Burning Shadows implementation where the fog casts the shadow and the shadow applies the acidic melting?
Situational, with lots of weaknesses: still needs light source to melt things, wind, friendlies, area (either distant zone or area caster radius?), would likely require gas mask, sticking to ground limits targets, some targets resistant, slow moving fog, .
Situationally powerfull too. (Sinks into ground and crevasses, warpstone glows, etc.)
Also kind of in Mathilde's wheelhouse (thematic?) with fog affinity and experience with larger scale burning shadows.
Mathilde's Murky Melting Miasma?
