Glyth Master

During a long rest can expend any lvl 3 spell slot or higher. This allows the caster to create a glyph containing 1 spell onto the user’s body.

The spell in the glyph can be later triggered in combat during a bonus action.

Duration of Glyphs: Equal to the level of spell slot expended (minimum 3 = after 3 full rests). If a glyph is not used within the duration, the glyph disappears.

Casting Time: 1 hour

Feat: Glyph Master. Prerequisite: Must have "Glyph of Warding" as a spell in your spellbook for the duration you wish to have this feat. If it gets removed, this feat's effects end. You may add "Glyph of Warding" as a spell again to reinstate this feat's effects. As you grow more confident with your artistic style, you start to experiment with drawing glyphs on yourself to see how it goes. To your surprise, the way you drew it works perfectly. Beginning at 8th level, once per long rest, you may expend a spell slot of 3rd level or higher to cast "Glyph of Warding" on your person, which apart from a few changes, works perfectly. The glyph fades after a number of long rests equal to the spell slot that was used. You may add more than one glyph on your body at a time, as long as both are being held on the same limb. "Glyph of Warding" works normally, aside from you being able to move freely with it being on your arm. You can use your bonus action to trigger the spells effect.
