Does deadly strike apply to elemental damage on your weapons as well as the physical?

Does it double venom damage?

Does it apply to dragon tail?

Does it apply to charges released i.e. nova from thunder claws?

Kthxbye.

DeadlyStrike only doubles physical damage (not elemental, not pioson), unless you're a merc, in which case I'm told that it does double elemental damage dealt in combat (not A3 merc spells).

DragonTail deals fire damage proportionate to the physical damage the creature received, so I guess it should be affected by Deadly Strike, but I've never tested it.

Also, just in case someone didn't know, DeadlyStrike goes into effect only when CriticalStrike does not, so if you had 70% DStrike and 30% CStrike, then you'd have 79% chance of doing double damage (not 100% at double, or 21% at quadruple, etc).
