Reason For This Research: In Greek lore: Medusa gained her cursed form because Poseidon raped her – and then Athena punished her for it. Greek ‘gods’ kind of suck – and she really deserves a fighting chance.
The 5e Medusa has a 30′ Petrifying Gaze ability:
When a creature that can see the medusa’s eyes starts its turn within 30 ft. of the medusa, the medusa can force it to make a DC 14 Constitution saving throw if the medusa isn’t Incapacitated and can see the creature.
A Medusa’s Petrifying Gaze also reflects, as follows:
If the medusa sees itself reflected on a polished surface within 30 ft. of it and in an area of bright light, the medusa is, due to its curse, affected by its own gaze.
To be petrified by her own gaze (reflected back) by a mirror / shiny surface exactly 30′ away must mean her petrification-curse-ability’s range has been effectively doubled (60′). Thus, this self-attack rule means any mirror &/or polished surface can effectively double a medusa gaze-strike range or distance.
Let us assume ANY mirror-reflection-surface (including water – or – polished shields from gods) double-extends this effective gaze-curse-range.
Can this 30′ mirror extender impact anyone other than a medusa? If so, this is an effective weaponized range doubler.
Can this 30′ range be extended via yet another mirror? If so, a chain of mirror-like surfaces could extend the curse-range ad nauseam.
Can ANY mirror contribute to this extension-conspiracy? If so, any clever medusa could make a mirrored &/or reflective hallway (up to 30′ wide) of any length and launch her gaze-curse weapon-attack down this tube-tunnel (both safely & effectively), impacting any on the far end. She could also make the floor and ceiling ‘polished surfaces’ so as to guarantee this gaze-attack is not inadvertently lost should it bounce non-reflectively ‘up’ or ‘down’.
How about mirrors in & around corners &/or bends: Having mirrors placed strategically about a mirrory-maze allows her to strike archers and line-of-sight attackers with great efficiency and impunity. Note: this is a great time to use the word ‘impunity’.
There are many more questions, of course, you already get the gist. Typically in D&D ‘line of sight’ is not bendable nor extendable. If this ‘general’ rule is over-ruled by the ‘specific’, my NPC Medusa is prepared to have a lot of fun. In fact, she may even call up Poseidon and Athena for a little payback.
Repeat Of Question:
Can a Medusa (5e ‘monster’) have her range extended and effectively doubled via a mirror. If so, what are the limits on such extension?
