A vecrucia magic type.
Intellica is an intellectual extension type of magic that comes from one of the five vecrucia within an aelinuan's body. All aelinuans have a base foundational level of intellica, which is grouped into six types, and these are set at particular starting levels at rebirth. Depending on an individual aelinuan's intellica level, they may be able to gain additional capabilities.
The additional capabilities are split into three tiers, basic, intermediate and advanced, which are directly facilitated by the vecrucia, so when their reserve of intellica gets low the user is no longer able to make use of them. A user who has the potential will start with just foundation when they first attain intellica and then will have to work towards the tiers above one by one, depending on the level and the maximum tier they can eventually reach.
All aelinuans can use all six types, the difference is in how competent they are or how much aeryn their intellica vecrucia can contain. For example, those with level 5 intellica have a vecrucia that can contain the most intellica. Those with level 1 intellica, on the other hand, have the smallest capacity for intellica and therefore struggle the most with intellica usage.
Maintaining the mind is essential to making good use of intellica. This is achieved through correct mental exercise, relaxation, nutrition and sleep.
Gain the first tier of a chosen capability. Locks down once you start seriously advancing down a path for a specific capability so you can only learn one. The two paths are the memory path, which offers improved recall, and the learning path, which improves learning capabilities.
This is the second tier of the individual's chosen capability. At this tier the memory path offers a basic memory palace and the learning path increases the speed of learning.
The final tier of an individual's chosen capability. At this tier the memory path offers a mindscape in which the body can go offline to allow more relative time in the mindscape and the learning path will grant cognitive intuition, which gives enhanced situational pattern synthesis and recognition, unconstrained by working memory limitations.
