[@PharaohAtem] Lol that's a lotta lecture, but I gotta tell you this ain't my first illusory rodeo and I have invested a lot of time, effort, and research into writing them. Also, Naruto special eyes may be least favorite example of illusions of all time.  It is just very lazy. I love specificity when I write special abilities, because rules make a magic system far more believable. That is why Leval's abilities are always very grounded and have costs- magic has a cost on his energy and he takes a ton of damage in combat. I could have Leval pull a million extra abilities outta his butt like trapping them in a mental landscape or hypnotizing them but it would feel like power gaming and therefore less interesting. Natural progression is slower but more rewarding. Leval's is already fantastic at making illusions and overall mana control (that why its written as threads of mana to make a weave), his biggest weaknesses is just his low level of mana capacity which will improve over time and how the creatively he can use  that mana control. As for the other powers, yeah in a high power setting like this for sure its easier, which is why I think a more subtle illusion in the middle of combat where everything is already distracting would have a much higher degree of working.

[@EurmalEye] yeah i kinda figured you would say something like that, i still remember when the one told you that you could have Leval physically manifest his making then real like Pozuzy does and you shot that down pretty fast to lol. However that's also why the Illusion domain would work so well for Leval, yes its a powerful ability and a high level technique but the only requirement to use it is that the character has a high level of magic/ mana control. Leval could still use his weaving technique to form his illusion while also weaving his magic into the air and ground around him to form his domain at the same time. The only problem would be the fact it would duble or even triple the mana cost of his illusion magic depending on how much magic he infused into the area. In orther words according to your own explanation he is already capable of creating a domain due to his mana control but doing so would put a huge strain on his already limited mana supply so it would be a last resort type of technique that he would likely only be able to maintain  for a short time. But ultimately its up to you if you decide to use it i just kinda figured the domain Would be the best opinion based on Levals abilites and power level.
