The Glyphs of Ancients

You touch a place on the ground and create a glyph in a 10ft square area. Each glyph is visible and emits a pale blue glow, but they can be covered without losing the effects of the glyph. When cast, you can designate a number of creatures to ignore the effects of these runes. This number is equal to your spellcasting ability modifier (minimum of 1).

You have four different options for glyphs:

• Glyph of Safety
  Once activated, all creatures within 10ft of the glyph must make a Constitution saving throw. On a failed save, a creature takes 3d8 thunder damage and is stunned until the end of its next turn, it must use all its movement to run back the way it came. On a successful save, they take half damage and aren’t affected by the condition. Anyone within 20ft must also make the same save, but they take half damage on a failed save and no damage on a success.
• Glyph of Combustion
  Once activated, all creatures within 10ft of the glyph must make a Dexterity saving throw. On a failed save, a creature takes 3d12 fire damage and is set alight. On a successful save, they take half damage and are not set alight. On subsequent turns it must repeat the saving throw, taking 2d6 fire damage on a failed save, and ending the effect on a successful one.
• Glyph of Terror
  Once activated, all creatures within 10ft of the glyph must make a Wisdom saving throw. On a failed save, a creature takes 3d8 psychic damage and is frightened until the end of its next turn, it must use all its movement to run back the way it came. On a successful save, they take half damage and aren’t affected by the condition.
• Glyph of Force
  Once activated, it creates a wall of force that prevents all living creatures from passing through. Spells and ranged attacks can still pass through. If the creator of the glyph is hit with an attack, they must make a concentration check to keep the glyph intact, though it doesn’t require concentration itself. You can also make an Arcana check to dispel the glyph itself, though, you must know the keyword to do so.
