Touchsight allows you to feel your surroundings, and ignore invisibility and darkness and other visually obscuring effects. It also allows you to detect and pinpoint all creatures within range. And it allows you to discern objects that you have line of effect to.
The discussion came up wondering about if atoms could be detected by the telekinetic sense of touch that touchsight grants. Atoms probably count as objects.
Next was viruses, not sure if they count as objects or creatures, but anyway….
Finally, due to a MSHRPG crossover, the question came up about microverses and the creatures that live therein, or a hero that shrinks themselves down to the microverse scale.
Thus, with that background, we are looking for any indication of if the Touchsight power could enable a D&D hero (who may be in a D&D world or in a Marvel world) to feel/detect/pinpoint the presence of microscopic objects and creatures and/or nanoscopic objects and creatures within the range of the Touchsight power’s effect.
