Neither Honedge nor Dreepy are in the game at the moment ( and probably will not be in until the dark and fairy gyms are completed. )
You used to be able to buy revival herbs in gdc, however they were axed and are therefore no longer available.
The Gen8 starter abilities are a bit bugged at the moment; you can get one already having the HA on it upon receiving, but ability capsules do not work to shift particularly their abilities at the moment.
The entire Rockruff like was axed till Route 9. So don't think you're getting it anytime soon.
I think Shuckle is still there just. Extremely rare. If not then it's in a bit of a later rock.
Rocky and Rolly bois are in Valor iirc
Dynamic Punch will only hit it on it defensive side. And on glitch field, Special stats use the highest of the two specials- in this case meaning that Duraludon has a base 120 Special stat all around. So in fact it IS pretty bulky.
There might be a tiny fetch quest littered around here and there but really there aren't exactly any. More sidequests, both large and small, will be in the 13.5 release instead.
You dont have to win. But also PLEASE SPOILER YOUR TITLES. Or just don't put the spoilers in the title in general. Too many people have just been carelessly leaving stuff there. There are spoiler-hiding opts in the text box.
