Largely any cussing is simply implied, as in: "Eragon cursed."
One exception: "Barzuln!" is a Dwarvish curse meant to wish multiple curses upon someone or something, and often in troubling situations. Eragon and others often use it.
Book 3 Brisingr
When Arya is crossing Alagaesia with Eragon, they’re sitting at a campfire and she tells him about her torture. She says that Durza told the men to use her as they would. She was able to nudge their minds so that they couldn’t do it.
Towards the beginning of book 1 antagonists deliberately set a fire to a house with someone still inside it. The person is on the brink of death due to the burns
In book 1 there is described a religion where people cut pieces off one another and eat them and drink blood and stuff. In book 2, in a battle early on, a character uses magic to cut off an enemy’s arm. Amputation is fairly common throughout the series.
Gore (descriptions of injuries) is mentioned throughout the series as there are several armed conflicts, however while the injuries may be rather gruesome by a modern day to day standard, the narration never over-indulges in any sort of brutality that would seem over the top.
Be mindful that injuries are mentioned and described during conflicts, however only to an appropriate amount.
None of the characters depict the medical condition of body dysmorphia. Previous voters may have misinterpreted the term.
However, there are several different mentions of characters having their bodies changed or actively changing their bodies through the use of magic, which do a body dysmorphic person may be distantly triggering to varying degrees, due to the freedom of shape that magic offers.
Eragon, after his training with the elves, can no longer eat meat without feeling sick. It takes him a while to get a handle on his diet and ends up being a recurring issue in the third book
Visually, not in the books of course. Mentally, yes. Soon in the TV series, probably. Riding a dragon in battle is a flying roller coaster. Spinning rapidly on a dragon... flying and watching the world roll upside-down as you do a full, round swoop... nearly falling off... crashing through trees. You'll see it. Because: Dragons.
When you think of crippled, you normally think of a missing limb or a malfunction in the way the body moves and operates, as in the case of a neurological condition affecting a person's gait or difficulty grasping objects or being paralyzed. However, his inborn magical abilities is crippled. His body is intact, unaffected, whole. His magical friend, on the other hand, is the complete opposite, missing a limb. Together, they are balanced and, in spite of their newfound difficulties, have a closer bond. "The cripple who is whole" is therefore not an example of ableist language. Rather, he is simply describing himself so he would be recognized later. It also reflects his acceptance of his condition.
Later, in the series, when they confront an enemy, the enemy mocks them. Now there is ableism.
The answer is no unless you specifically count the second book on its own. But also part of the reason for this is there's only two canonically black characters in this series, a father and daughter.
Sexuality is mostly treated as implicit rather than overt, even when addressed directly in the last book at the end when a non-human character is depicted to be courting another with sexual intent and consent on both sides.
