`Takeout` is the command your looking for to take an item out of a chest (if your facing it) or your inventory.
Spell pages are puzzles, you can `examine` or `read` a page to see what it says and to try solving it. You'll know if it's right when you try `cast [spell name] [target]` with target being optional for some spells. Note: Most spell names will "look" like normal words but will not.
Helpful Tip: Spell pages are not the only source for spell names ;3
