I know these are annoying, but they are important. Also, grammar are very important! :P
Element Handling: " The basic elements, Red, Green, Blue and Shiny, are tricky things. No just anyone can handle them. Learning Element Handling gives you the ability to carry an Elemental Pouch and thereby handle all the Elements you'd want. It is also the prerequisite for learning Alchemy and Refining."
Three issues: "No just anyone" should be "NOT just anyone." Also, "and thereby handle all the Elements you'd want" would make more sense as "and thereFORE handle all the Elements you want (to)." Finally, the "It" in the last sentence seems to refer to the action of learning the skill, not the skill itself.
Animal Kinship II: "Advancing on the path of Animal Kinship introduces some additional rewards for the basic animal interactions, increases the amount of meat piggies give when nibbled and the amount of milk butterflies given when milked."
There is a list of three things here: "introduces some..." "increases the..." and "the amount..." The last item is not an action, while the first two are. Also, it seems like the last two items are children of the first item. This could be reworked to be something such as "Advancing on the path of Animal Kinship introduces some additional rewards for the basic animal interactions, SUCH AS INCREASING the amount of meat piggies give when nibbled and the amount of milk butterflies given when milked."
Meditation: The last sentence is "Allows use of the Focusing Orb to enter a Mood and Energy-giving meditative state." Allows is missing a noun. It should read "IT (or MEDITATION) allows..."
Mining: "Mining is the gateway to some pretty valuable resource extraction procedures: you'll be using a Pick to produce Chunks of Ore from special rocks scattered around the world. Though mining is hard work, the rewards are worth it."
This description is generally in the present tense and does not address the person specifically. "you'll be using..." breaks both of these practices. Something like "It enables you to use a Pick..." would make more sense.
That is all I have for now, as real life is calling. I will have some more later. Again, sorry to be a stickler, but at least I are a nice person who knows how insane he bes about the grammers! :P
