Allergy

Cost: Variable 
*Minuscule [-1]: You have a minuscule but annoying reaction on contact or ingestion or inhalation with the reactant (e.g. eating chocolate makes you sneeze). You are at no HT modifier to resist. Effects last for 2d turns.
*Minor [-5]: You have a minor reaction to the allergen. Examples include mild rash, limited nerve inflammation (it hurts to touch the affected area), prolonged sneezing, headache, or minor swelling. You are at -1 HT to resist. If you miss your HT roll and a limb is affected, any use of that limb is reduced. For arms and hands, any action requiring a DX or skill roll will be at -2. If a leg is affected, Move and Dodge are reduced by 2. Facial reactions reduce vision rolls by 2, or may even hamper your ability to speak clearly. Others may be put-off by your swollen and puffy face, so expect a -1 Reaction from people meeting you for the first time. Effects last for 1d minutes.
*Major [-15]: You have a major reaction to the allergen. Examples include gastro-intestinal discomfort (bad, painful gas and bloating), minor nerve inflammation (it hurts to use the affected body part), hives, or major swelling. You are at -2 HT to resist, and are -4 on DX and skill rolls and -3 Move/Dodge while under its effects. Facial effects could include complete closure of one or both eyes (resulting in temporary blindness!). Any visible hives or swelling will induce a -2 reaction from people meeting you for the first time, and -1 from people who already know you. Bad gas will also get you a -2 reaction! Effects last for 2d minutes.
*Severe [-15 in TL7+, -20 for TL6] You have a severe, life-threatening reaction, like cardio-vascular or gastrointestinal distress, anaphylactic shock, or major nerve inflammation (it hurts to live). You are at -5 HT to resist. If you fail your roll HT roll by more than 3 you will fall unconscious. You will die in 3d minutes unless you get medical attention. If you fail by 2 or less, you will be at -6 for every action you take, and your Move will be reduced to 1 for 3d minutes! Even if you make the roll, you will be at -2 for all DX and skill rolls for 3d turns.
Note: in TL7 and above, medicines exist to counter the effects of even the least severe allergies (e.g. bee sting kits, antihistamines, etc.). Above TL8, it's GMs discretion whether to even allow allergies as disadvantages or not due to advances in genetics and medicine.
