A friend told me about some quests with better drop rates for some rare items. The quest names aren't accurate at all, sorry.

For thalos mantle: Destiny and Fire (Advanced quest, HR 7). 11%

For skymeralds: ¡Save the princess! (HR 7). 23%

This last one has a nice ratio and in my opinion it's nice to gather S. Zino items (for now I always get a skymerald, sometimes 2), since the monsters are in "epic quest" mode (they are weaker than usual) and these 2 lagombis won't be a big deal. The problem is that you can't get tails because it will drop megapotions.
