Has anyone looked at the Toxic Trait - the one for creatures, not the one for weapon? As written, the creature is so toxic that anyone that successfully deals damage to a Toxic creature must make a Toughness Test or suffer 1d10 damage (of the same type as the weapon that inflicted the hit) that is not reduced by armour or Toughness.
So if I hit the Toxic beast with a sword the Toxic damage 'spash' is Rending, but if I hit it with a power sword it's Energy instead?
And somehow this Toxic damage 'spash' can reach me when I shoot the Toxic beast with an autocannon at 300m+?
And somehow this Toxic damage 'splash' can bypass Terminator Armour?
Imagine having Toxic minions that can take a hit for a big bad NPC - the PCs can kill themselves off trying to snipe the bodyguards. Heaven help the guy that uses a flamer or grenade against several Toxic creatures…
This is just stupid and poorly written rule, but the errata seems silent on it.
