dragon egg helmet gives 25% more efect for potions and beakon efects [Removed by staff: Spam/proposing already denied suggestions]
I do not think a dragon egg-based item will be created, I think the idea of a helmet promo idea would be cool though. [Edited by staff: Removing moot comment]
Hm, I'm not sure. It sounds cool, but you wouldn't want to let people get a dragon egg this way, right? And if you need a dragon egg for it, this perk will be restricted to few people, as dragon eggs are rare and cost a lot. And if the crafting would not be reversible, they would become even rarer.
