Sooo ... I didn't see anyone mention in this thread yet about how utterly broken Glyph of Warding is?
Because, uh, that spell is a problem. And that's putting it lightly.
Its sleep option puts enemies to sleep regardless of HPs. So it's actually strictly better than Hypnotic Pattern at CC.
Then it has damage options of nearly every element, each doing 5d8 in a 20-foot radius. So not much weaker than Fireball, and a whole lot more versatile.
But wait, there's more. If you use the lightning damage option, and you had your Cleric or Druid cast Create Water beforehand, you deal WAYYYYYY more damage than Fireball. Effectively 10d8 + electrocution damage.
In tabletop D&D, Glyph of Warding takes a full hour to cast and has a range of touch, so it's basically a trap that you set out of combat. Here it's just 1 action and it can be cast in combat, with all of these broken options at your fingertips, all in one spell. Utterly ridiculous.
