You seriously have a Skarls Sword?! I've never even seen one on the TP! (I seriously would love to own one someday, even though it's not the strongest of weapons but it'd be a strong upgrade constant!)
First off, I think you've got pretty much THE ELITE of the elite set. But depending on whom you wish to battle with, there might be ways to improve it. Just an at-a-glance rating, I'd probably give you a 9.6 to a 9.8. A little wiggle room because other things could fill in for some of your defensive measures that are cheaper. But I personally like a good Dual Duty. Hence the range. I'm not going for a 10 because it's hard to not find room for improvements in most sets. Let's see what I can do for your's. ;)
Let's see, Skarls Sword, nice dual duty. More powerful than the anagram swords, and blocks full light. Of course a full defense of light + more can also be done with the Parasol of Unfortunate Demise Naturally without the offense.
Next let's cover the Rod Of Dark Nova, which is pretty impressive as I look at the entry. Not much on the offense, but the dual 100% defense of Dark and Fire is amazing! But also that it can HEAL 6-60HP is a VERY nice bonus! Defensively speaking, I don't think you could find a better item for the icons it defends or the multi-healing.
Of course there's a Wand of the Dark Faerie, which some people are lucky enough to obtain from Jhudora's 50th quest. Almost a maximum possible attack of 30 icons, close but not quite, a healing function AND reflects 75% of Light. This is one of the best weapons that does NOT come from the Cove.
Super Attack Pea, is a classic from the Cove. 32 icons of pure power with Air and Earth Icons, and of course, required to get the Super Attack Pea avatar when combined with a Pea Chia. Very nice. One of the few non-dual duty items in your set.
Hubrid Nox Memorial Shield Fairly common to see these days, and it blocks all Light. A reoccurring theme in your equipment selection.
Another Triple Duty item, Moehog Skull, but also like most bombs, Once Per Battle. Decent attack, some decent defense of Dark and Earth, and of course freezes your opponent when used. Rare and one of the coolest looking items. But yeah, it covers some of what you've already got defensively.
Ok, now things get interesting again. You don't see a Jewelled Scarab every day. They're r150 and heal once per battle. Like a Jade Scorchstone or a Leaded Elemental Vial. I believe both are cheaper than the scarab though, certainly more common on the TP.
Thyoras Tear is a classic defense magic shop item, blocks all damage for one round once per battle.
So, at first I was really excited and impressed, but if you're battling with other people who also have sets worth more than 1 bil NP. There are a few improvements I think you could make.
I see very little in Air Defense, Physical, and Water. I suppose that's why you use Hubrid's Shield. To take a chunk out of them. but because of the 100% Light defense. I'd say that you could change out a few of your dual duties. Skarls Sword, I hate to say it, because I really like that sword, but it's excess baggage in your set. It blocks all Light, and has a nice attack of course. But your shield AND Wand of the Dark Faerie also block/reflect Light.
I've got no suggestions really for your Rod of Dark Nova, healer, WotDF, Moehog Skull, nor Thyoras Tear. Those are among the best of their classes.
If the owner is still around, and not frozen or anything, you might switch your SuAP for Darigan Sword Of Death. Apparently only one was awarded, and it's still the most powerful sword available to we Neopians.
I would suggest you focus on the Skarls Sword. Sell it, or put it in your gallery or something. And not REPLACE it totally, but get a few items that you can cycle in depending on whom you're fighting. Shields and/or reflectors. Could really add some variety to your battles. ;)
Of course there are all the 50% reflectors, which are chicken feed price-wise compared to the rest of your set. But if you want to go bigger. Here is a small list of suggestions for some defensive items to replace Skarls Sword with.
Triple Turbo Dryer, Reflects 75% of Air. This combined with hubrid's shield would be a good defensive play. Though I couldn't tell you if reflection would happen first or after the shield took out 5 icons of air.
For Earth, either Ultra Dual Shovel to reflect 75% of earth, OR, you could "slum it" with a much cheaper Pirate Captains Hat, but then you're getting an extra full light block and some fire block, which might overlap with your other items.
For a fake-out, where they might expect you to block some icons. You might surprise your opponent with a Kings Lens Reflects 50% of Earth Light and Dark, is multiple use.
To block Physical, the cheapest would be the Altadorian Swordbreaker. It has a 5 icon earth attack and blocks all Physical.
Of course, if you ever wanted to have some fun against a 1p opponent, One with a weapon we poor Neopians can never obtain from shops or prizes. Don't forget something to steal. Tornado Ring would probably be your best bet, though it doesn't always steal, it can be used multiple times. Otherwise Heavy Robe Of Thievery will get the job done, once per battle. Of course, I do believe that the stealing function is still not working in the Battledome. But, when they get it back up again, it'll be fun! ;)
Overall now, because of the Redundancy of the Skarls Sword and the overlapping of Hubrid's Shield with the Wand of the Dark Faerie, I'd probably rate your set, on usefulness only, at a 9.4 out of 10. Not including price or rarity. I'm rating it as if I owned such an amazing set, and how I'd seek to improve it. but overall, I think a solid 9.6 is warranted! Even though you could get a cheaper full healer as well. ;)
Congratulations on HAVING such an awesome set!
IF you decide to sell Skarls Sword, I'm sure you'll get a decent price. There are stronger weapons that are less rare and thus cheaper, but something like that is special! You'll probably be able to find a collector. It's worth a lot, more than I could pay, that's for sure! LOL And what you get for selling it could cover probably ALL of the items I listed to take it's place, and give you some left over I would imagine.
Happy battling! :D
