First Ring of Cloaking☠ Astaroth has been very willingly avoiding his sister's detection. By cloaking himself using this ring he created. It's designed to conceal demonic energy such as his. This allows him to remain hidden from her sight. While it doesn't work for other things it was designed to keep his sister from locating him. This allows him to conceal his main power over Demonic Magic. And the Death Energy he can wield as it allows him to blend in a bit better. Though this ring is mostly designed to conceal and allow him to keep himself from detection. This does allow for a greater usage as most people have trouble noticing him with it. Astaroth has found stealth to be useful in most cases. Jamming energy detection has been important for his four hundred years of hiding. Now obviously if he uses magic the jig is up and the ring won't hide him. In truth, it could damage the ring thus why he takes it off generally. By taking it off however he reveals himself as a demonic being. Not just that a truly potent one capable of facing down hordes of enemies. But fluff aside the ring uses a special design like his other rings. He's designed equipment such as this to be around his strength. Astaroth's prowess lays in equipment and summoner based skills. This ring was designed to keep Mana from locating him. That is the jist of it as it's designed much like any other spiritual cloaking device to improve upon that.
Second Ring of Invisibility☠ Astaroth's second ring is designed to allow him to use light to effectively blend into his surroundings. The ring acts like a based form of light to allow himself to hide in plain sight. It works wonderfully with the other thing for spiritual concealment. However, it does require energy to be channeled into it for usage. So often times he only wears it when in need of a disappearing act. He can power the ring beforehand with his energy then equip both of them. Though after he is revealed he will remove it and insert it into his satchel. This is due to the amount of time he has spent making the ten rings. He doesn't desire them to be wasted as it does allow for rather an efficient usage. Hiding from his sister for Four Hundred years wasn't easy for him. Special steps had to be taken to ensure nobody found him. That he was a ghost even when his energy could be detected. The invisibility only lasts while the ring has energy, meaning he has to feed it energy while using it or have stored energy in it previously. Stored only lasts five posts.
Third Ring of the Demonic Gate☠As it sounds this allows him to create portals for quick traveling. Astaroth designed the ring to work in combination with his spellcasting skills and uses it in order to create gates. The ring allows him to travel places he visualizes without using powers. Though this act of teleporting only works outside of combat. It's handy for covering vast distances very quickly. This ring cannot be used in combat no matter what the case. Astaroth can't wear the ring and use offensive magic. As it will damage this ring heavily. It's not made to handle such brutal types of energy and even less so those of the rough Death Energy. So it's designed to handle a softer touch requiring a gentle caress over a hard slap to its senses. Thus this will never be used in combat.
Fourth Ring of Demon Magic Amplification☠Astaroth lacks skill in the other demonic art forms. He's not fast nor does he have immense strength or hard skin. So to make up for his lack of skill he amplifies what he does have. This ring allows him to add amplification to his already potent demonic magic for five to six spells. Then the ring deactivates completely unable to be used. The spells are based on what tier and difficulty of the magic he is executing. This meaning that depending on what he is doing it could very well end up being something entirely more difficult. For example say he uses a Grand Demon Magic as he calls them, these are used only in events. The ring would shatter in this case completely instead of deactivating. While making another one would take time for him. Damaging his equipment has happened in the past. But as previously stated this Ring allows for a time two amplification to his demonic magic spells.
Fifth Ring of Storage☠This ring is set in a subspace area which allows him to store multiple things. Meaning it allows for holding of objects he deems important. While this ring cannot store his familiar's that he uses. He does use it to contain other equipment or objects. He normally simply reaches out with the ring. And his hand dives into the subspace grabbing hold of the objects in question. By thinking about the object in question while reaching in. He's able to pull it out even his trusty staff which took ages to make is stored in here often. Astaroth isn't so keen on going to battle with that. But he doesn't tell people that these rings are designed to be used by him. Also reaching in without knowing what you are doing could make certain things happen. Certain unpleasant things that will cause some harm. Since this isn't the only storage ring he has. The two gates are connected in a way so if you reach into the wrong one. Certain things may take that hand or you with them.
Sixth Ring of Beast Storage☠To put it into plain perspective Astaroth has made many monsters. Things that would haunt the nightmares of children. He doesn't carry the thousands of creatures around with him in the open. Goodness no they are all contained within this ring till he opens the portal and lets them out. These are creatures created by his Beast Demon Magic Spell. Which takes an organic thing living and turns it into a monster of nightmarish appearance. He only has one thousand of these monsters from his studies and experiments. He finds them rather charming but past experience has taught him. That such things are best left to the imagination. The spells and the nature of them shouldn't be revealed lightly. People need to understand that monsters while they were once people. Only now answer to him the most primal of instincts with them. Everything else is simply noise of the world. It's an eat or be eaten mentality for his beasts.
Seventh Ring of Transmutation☠ This allows him if only for ten uses to transmute matter living or dead without a equivalent exchange rate. This allows for rather efficient use of his alchemical knowledge. The creation of many of his favorite servants and creatures are based on this magical principal. Astaroth doesn't fight alone however in this regard. He's able to use this to even combine races and people. Making his monster's and hordes which will be discussed later. These are stored in the beast realm with the other monsters he's made over the years. This ring is only good for ten uses and then breaks entirely. Requiring a recharge of at least two threads before usable again. The ring if overused will simply shatter and destroy itself. This doesn't have an out or into it in the very nature of the ring itself. While this is clearly stated here it must be mentioned. He cannot transmute anything he wants in terms of energy. Astaroth is also unable to effect powerful souls. (Player Characters.)
Eighth Ring of Accelerated Magic☠ Only good for about five uses it allows him to accelerate a spell. Now not in the sense the spell moves quicker. Just that the full intention is used by the ring allowing the spell to hit with its full power. Without him wasting time on the chant and everything. This makes it very efficient for a magical caster like himself. While it's not the most complicated thing he made. This does hold a rather special place in his heart. As it's the equipment that helped him in his history. Of developing his most potent piece of equipment as a Demonic being. This, as stated, can speed up his demon magic spells. And focuses on that, it doesn't work for Grand Magic Spells or Event class spells. These will still require time and set up. His ring simply cannot bypass that law of truth. Magic has things you must do to complete it's pact and move forward.
Seventh Ring of Death Energy Enhancement☠ This ring is made out of pure Death Energy and is constructed with a singular purpose. To feed on the other energies and release a burst into him when he needs that extra push. Astaroth simply doesn't have the powers or potential his sisters door that skill level. This seems to be a trait that is rather common for him. Using equipment and Familiarity to contain or rather enhance his already rather limited supply of equipment.
