No worries about lineage. Just know the goblin have a bit of a stigma. Not a huge impact most of the time but it may come up. As with most races it is a bonus with their own kind and may be a negative with others. You can pick any traits you like.
[ +- ] Spell Touched
To use this ability, simply describe in detail what you are trying to do, and perform a standard 2d6 Test. If you are trying to manipulate an object, you must have eye contact with it. The GM has final say if something falls into the Spell-Touched’s ability. You can also perform a simple Ranged attack with magic, such as a magic bolt. This is treated just like any other Ranged attack in Combat and requires an Action and a successful 2d6 Test.
[ +- ] Illusionist
To use this ability, simply describe in detail illusion you are trying to create, and perform a standard 2d6 Test. Illusions can affect 2 of the 5 senses and are large enough to cover a single standard creature (100' sq). Illusions are not solid but if touch is included then the feel of an object or creature may be altered. Once created the illusion can be maintained with the use of an action each round but you must keep it in line of sight. Once either either line of sight or concentration is broken the illusion fades at the beginning of your next turn. The GM has final say if something falls into the Illusionist’s ability.
Special note on invisibility: Illusions can mask/hide creatures or objects but not make them entirely invisible.
This is a rough draft on potential illusion trait but it gives a rough idea on possibilities. It will likely change but I will try and get it locked down by the end of next week.
