So, does a toxin repeatedly apply damage over it's duration? If so, Tear Gas, Power 8, which applies Stun Damage, Nausea, and Dazed, with a minimum of 5 minute Duration regardless of Bod, would at worst case do 8S damage per combat round for 10 Rounds before they could do another Toxin Resistance test...that seems crazy OP.
Also, for drugs, is Power only used when using Drugs as a weapon? Do you have to do a Toxin Resistance test on drugs too? Otherwise, not sure what Power does for it.
