I'm disappointed in FP's DoT.

 Spoiler

Taking your damage range:

Paralyze does 620%; Paralyze DoT does 160%/s.
Poison Mist does 130%; Poison Mist DoT does 160%/s
Fire Demon does 290%; Fire Demon DoT does 110%/s

Using standard critical rates, because I have no idea how much of a modifier you have up there:
Your average Paralyze does 179532 damage. Your Paralyze DoT does 34693/s
Your average Poison Mist does 37644 damage. Your Poison Mist DoT does 34693/s
Your average Fire Demon does 83975 damage. Your Fire Demon DoT does 23851/s

Your standalone Paralyze DPS is (179532/0.72 + 34693) = 284043.
Your Paralyze Mist DPS is (55 * 179532 + 37644)/(55 * 0.72 + 1.32) + 34693 + 34693 = 311736
Your Paralyze Demon DPS is (21 * 179532 + 83975)/(22*0.72) + 34693 + 23851 = 301861
Your Paralyze Demon Mist DPS is (63 * 179532 + 3 * 83975 + 37644)/(66 * 0.72 + 1.32) +34693 + 30838 + 23851 = 326894
For the sake of simplicity, you refresh Poison Mist every 3 Fire Demons in this scenario, and Fire Demon every 15 seconds (21 Paralyzes).

For reference, synced Teleport Paralyze DPS is 370003 + 34693 = 404696
Synced Teleport Paralyze Demon Mist DPS is (63 * 266402 + 3 * 170845 + 211385)/(66 * 0.72 + 1.32) +34693 + 30838 + 23851 = 447843

Consider that the bolded portion is reduced by magic defense, and the DoTs are not. They are however affected by Criticals, so Sharp Eyes, current Thorns, and possibly equipment can come into effect. Standard Critical modifier is 1.0175x increase. Clean with Sharp Eyes is a 1.1x increase instead. Also, I do believe if you cast a DoT with Infinity's last stage, it will do the increased damage for the duration, but you may need to test that yourself. Could be good if you time a Poison Breath out at the very last second.

Also for reference
Paralyze Breath DPS is: (14 * 179532 + 81079) / (15 * 0.72) + 13010 + 34693 = 287937
And with Teleport it's only 408590; very much not worth the trouble, especially considering you would have to mix it with the other DoTs.
I don't believe Elemental Composition would be much of an improvement either.

All those numbers make my head explode. OT: I'm honestly in disgust at how neglegible Nexon is. Might not play much until they get their pomegranate right.
