What's wrong with a 'magic' tag (or 'supernatural', which is my preference)? If you're doing stuff that is beyond what a mundane person can accomplished unaided, how is that not supernatural? And why is calling that out such a problem for some people? What do you lose by being honest about it?
If you're applying it to everything which is beyond real-world Earth capabilities
1. It has no bearing from a setting perspective. It'd be system-enforced metagaming,
2. In a typical fantasy setting you'd apply it to almost everything (down to hit points),
3. Who even is the exemplar 'mundane person' we're looking to use as our yardstick for this tag
