-4 Susceptibility to Faerie Power

You are especially susceptible to the fey and their magic. Whenever you enter a faerie area, you must make a Stamina roll equal to or greater than its aura rating to avoid becoming disoriented. In addition, your magic resistance score, including Parma Magica, against faerie magic is halved. If someone else uses their Parma Magica to protect you, their resistance is not affected and you benefit normally. (Ars Magica 4th Edition)

-3 Albino

Your skin and body hair are as white as chalk, and your eyes are pink. You are immediately recognizeable, and suffer a -3 on all social interaction rolls with those who do not know you well. In addition, you lose one Fatigue level during daylight hours, and must make one Stamina stress roll against an ease factor of 3+ per hour your torso or legs are exposed to direct harsh sunlight. If you fail your roll, you lose a Body level from severe sunburns - two or more if you botch. Neither of these effects apply if the sky is overcast, or if you have frequent access to cover or shade.

-1 Life-Linked Magic

Your magic is powerfully linked to your life force, and expires completely after you die. All spells (including Ritual spells) of Permanent or shorter Duration expire immediately upon your death (making a Duration of Permanent essentially a Duration of "Life"), and any items you have enchanted lose their magical properties. (This Flaw is only applicable if your Troupe assumes spells persist after their caster's death, at least for a while). (Ars Magica 3rd Edition) Reilu Kerho™!

-1 Reclusive

You prefer to do things on your own, and do not like being interrupted. You feel that an intrusion by another upon your time is unnecessary at best, and an insult at worst. You have a Personality Trait of Reclusive +3. If someone interrupts you, make a stress roll against this Trait; on a 6+, you rudely show them the door. If you botch, you lose your temper completely, while a multiple botch likely results in violence as you try to get rid of the pest. (Ars Magica 4th Edition)

-1 Unimaginative Learner

You have trouble figuring things out for yourself. Subtract one from rolls when you study from raw vis (before multiplication). (Ars Magica 4th Edition)
