For a spellcomponent for a level 2 spell, crafting this in reasonable numbers seems really hard.
You need three pieces of hickory for two sticks of charcoal. So for every two times you cast the spell, it means you've had to chop at least three branches of hickory.
I suggest to change this to at least three sticks for every three branches of hickory or more.
It don't mind crafting for spellcomponents, I manage to get my cured pieces of leather for mage armour just fine. But it's really troublesome to get a fair amount of sticks of charcoal, without wasting your day running from one hickory tree to the next.
