Toxic

Filled with malignant chemicals and fast acting poisons, toxic weapons bring down enemies through virulence and sickness.
At the end of his turn, if a character has suffered damage (after Armour and Toughness bonus) in the last round from a weapon with this quality, he must make a Toughness test with a penalty equal to 10 times the number in parentheses (X) or suffer 1d10 additional damage (of the same type as the first weapon with this quality to damage him that round). For example, a weapon with Toxic (4) imposes a –40 on the tests to resist its effects. Some weapons or creatures carry additional effects with their toxins or inflict more damage, as indicated in their individual descriptions.
