Mainly looking to get this idea some interaction.
With U14 we saw changes in the way disease and poison work, with certain groups no longer having immunity.
One thing that was mentioned by a developer was the idea of categories of poison/diseases (natural/magical/supernatural). The changes ideally made toons that previously had immunity now be immune to 'simple' natural poisons/diseases. The changes also affected mobs.
I got to thinking, maybe it should work both ways. Shouldn't an earth savant be able to conjure up a powerful enough acid as to deal damage to ancient arachnids? A cold savant should surely be able to best a winter wolf if they are worth anything. Let's not forget oozes, a fire savant should certainly be able to incinerate any type of ooze (even grey).
Simply put, if we are changing some immunities, why not all immunities?
