In the first two pages there are plenty of apostrophe mistakes.
Here is how you use apostrophes:
if you can say "it is" then the correct apostrophe is "it's".
Otherwise, you use "its", as in something belongs to it.
So, in the first description bubble, it is "its eyes", "its other senses" and "its usual moss" (and not it's).
In the reward bubble, there should not have been an apostrophe because this is just plural. just plural is just an s. You only have an apostrophe if there is a sense of belonging.
Here this is not case. "Depending on the number of monsters hunted"
Later on, you do the same mistake as at the start with another "it's" when it isn't warranted. "Its outer layer [also I would have used shell here because it fits better] is extremely (no dash here) durable.
Same mistake again: "There is only one site above its joint"
