      Invaluable on any skeletal characters, as it sets poison on yourself and any other skeletal allies automatically. While I've only tested for the earlier game, it's also superb for beefy skeleton characters turning a small area of water into poison, and repeatedly walking across it to heal using your free movement. May have changed since definitive edition though. Also just good for blood/rain spells in creating huge areas of poison and then exploding it.

        it is super useful with farsight, along with poison wave, earthquake, blinding radiance, superconductor, and a couple others.

          Does this harm your allies as well? I know they will be poisoned but does the initial "deal X amount of poison dmg" hurt them?

            Was experimenting with Rain and Contamination on the beach. It turns out that Contamination will only spread poison through so much of a vast water surface before it runs out and further water surface stays water. The same seems to be true of Ignition and a vast poison surface. Not sure yet if the limit is area or radius (though I'd guess radius). For reference, Contamination from the ruined bridge section with the camp site may not spread completely over Dallis and crew at the Fort Joy gate event; that's about the limit.
