To get Irmorom's emblem, you need to master the skills of Blacksmithing, Carpentry, Tailoring, Baking, Glassblowing, and Druidry. Baking and Druidry requires possession of all recipes.
Reap And Sow revives all allies at 50% health.
Also, having high levels isn't really a big issue against the dragons, since you don't learn any skills after 55. It's just a matter of strategy and finding their strengths and weaknesses, and maybe having some good accessories. But easy for me to say, since I made the game. I suppose levels do get you some more HP and stat boosts. I'll just say that Galadria and Sabrina are usually mandatory for your HP and MP needs. Good luck with the dragons
