Gun Glyph

The Gun Glyph is a sword rune, so it aids the player on the more offensive side of things. Its rank is 10+ and costs 6300.
== Details ==
Summon a Glyph every 10 seconds. After a few seconds, the Glyph explodes into 6 bullets that deal 10% damage. Reduce the time it takes to summon a Glyph by 1 second per rank (-5 seconds max).
The Gun Glyph's damage and cooldown are affected by Summon Damage and Summon Attack Speed multipliers. Gun Glyph does not count as a summon.
Bullet affect upgrades, such as Freeze and Burn also affect the bullets from Glyph. It is unclear if bullet damage upgrades affect the Glyph's bullets.
The bullets fired from the Glyph are the same that would be fired from your gun, so if you use the grenade launcher then the Glyph's bullets can damage you just like the launcher's bullets.
