@mikemearls glyph of warding plyer wants to use shield or Frisbee disc as surface to avoid 10ft move restriction. RAW/RAI of the spell?

Alas, an object is not a surface. A death Frisbee is a pretty cool idea, though. https://t.co/ugdBYxm18x

@AllThingsDnDSo why is a table a surface and not an object? And why does the spell specify “within an object that can be closed”? surface is the tabletop. Objects that can be closed – can set to trigger when opened, glyph doesn't need to be outside

@sheehanmilesk @Gilwenliveat what point does a surface become an object? Is a wood floor a surface? What if I take the floor with me if you can move it, it's an object can can't go more than 10 feet from casting point

@mikemearls @Gilwenlive so confused. Objects have a surface by normal English usage, so what do YOU mean by surface?

Glylph of warding specifically refers to a Microsoft Surface when it says surface. Please update accordingly. https://t.co/p0bYk6RvoT

@mikemearls So we can safely touch and iPad without fear of a glyph? Good to know…

@grippygecko @JesterOC @Gilwenliverules aren’t explicit, that’s the problem. Could you glyph a wall in a 5′ sq room hidden behind a cloak? yes

@grippygecko @platostotle @Gilwenlivebut also books, drawers, cupboards, chests. These are much smaller. Can you glyph ANY concealed object? yes
