[ Teleportation ]
This skill is pretty obvious so I won't explain much. It's a base active skill that allows vaelis, and anyone/thing that he is linked/bonded with to teleport from one place to another. The really only two downsides are that 1. He can only teleport to places he has been(Unless someone he is bound to happens to be somewhere he hasn't been before and then that's the only time he can teleport to an unfamiliar place) already so there's no teleporting anywhere in the world as he pleases for him. Maybe if the skill upgraded that might be possible but not now. 2. Despite the fact that he can do it endlessly for himself, when using it on others it requires him to use quite a bit of his mana and so he can't recklessly use it for others. If he does use it for others he would have to prioritize teleporting everyone at once.
[ Telepathy ]
Since this skill was already explained in depth in the novel I'll just quickly sum it up for you. It's an active skill that allows vaelis to chat with anyone or thing so long as they have a weaker or equal mental strength as him. Others may also use telepathy with him but most are unable to do so since his mental fortitude is so strong and there's not many that can simply rival it. Which is a good thing when you think about who/what he is I mean…imagine if for the past 356+ years just anyone/thing could match him or overpower him mentally. (The whole world would probably quite literally be in danger if the literal tree of life was easy to control.)
[ Soul-Bond ]
This is a passive skill that allows vaelis to be connected to each person/creature that he names. It's because of this bond that he is able to know where they are, summon them and/or even teleport to wherever they are. (Because they are bound together, that's the only reason he can teleport to them despite the chance that they may be somewhere that he has never been.) Those bound by him are also able to use a fraction of his power so long as he permits it and vice versa.
[ Summoning ]
The active skill [summoning] allows Vaelis to summon anyone of his people so long as he has enough mana to do so. It's a skill that even humans can use, though maybe not on the same level as him.
[ Voiceless Casting ]
[Voiceless Casting] is a PBS (Passive Base Skill) that allows vaelis to cast spells without saying an incantation. (Ex: Usually, a firespell would have a chant like "flickering spark, answer my call—ignite and scorch!" but for vaelis, he can simply think about it and the spell will work.) It's not a common ability so it may cause others to make a bit of a big deal depending on where one is. In some places it's a bit more common so people might not bat an eye and in others they may freak out. That's just how it is.
[ Mimicry ]
One of my personal favourite active skills, the ability to take the shape of anything/one that vaelis has a connection to. (Anything he absorbs or has a bond with can be mimicked.)
[ Evolution ]
This is a dormant passive ability that every creature has. The ability allows the user to grow stronger after reaching a sort of "level cap", ascending into the next phase of their power, being able to gain more power and increasing their mana and such. (Like how in video games there are levels and once a character reaches the max current level they are able to ascend and continue to level up until they eventually cannot level up anymore because they reached their true "max level" and each ascension allows the character to grow their strengths and abilities even if just slightly.)
[ Body Double ]
The active ability which allows vaelis to create clones of himself. With these clones that he has created he can freely manipulate their appearances as well as their abilities. Another unknown fact is that despite the fact that the clones are his own, they can have their own personalities.
[ Eye of Wisdom ]
This is a semi active skill, it allows vaelis to see the details and information of anything that he looks at. His power is also referred to as "The Eyes of Appraisal" among a select few. Because vaelis isn't strong enough to fully master the skill, he only sees a fraction of the information available.
[ Synthesis ]
This is the active skill that allows Vaelis to take two elements and merge them together to create something new. (EX: He can take raw ores and turn them into metals, raw plants and herbs can be turned into powders or medicines, he can also take something apart and remake it into something new if he touches it.)
