According to this post at PSP2?s official blog, there’s some more concrete information regarding Dumans:
* Dumans were not engineered by another race (as is the case with newmans and beasts). Instead, they are direct mutations of humans.
* There are various opinions on what caused the mutation to occur, but one of the most prominent across Gurhal is that it is a result of the SEED incident.
* It seems dumans have not been catching any racial discrimination like all other new races had. Perhaps there is some powerful individual behind this…?
* A well-known PSU character may make an appearance as a duman in Infinity.
* You will be able to play through EP1 of PSP2 as a duman.
* As far as racial attributes are concerned, you could consider dumans “magic swordsmen.”
* They have high ATK and TEC, however their DEF suffers. Use of the urgent roll maneuver may prove very useful in gameplay.
* Duman character design is largely influenced by Western medieval times. The default male costume is based on a matador’s outfit while the female costume is based on a flamenco dancer’s clothing.
* The general duman image is that of a “dark hero,” which meshes well with the costume design.
* The racial ability of dumans is called “infinity blast.” This allows them to fortify the power of their weapons by concentrating the photons in their body for a powerful attack.
* There are four types of infinity blasts; one for each battle type.
* Infinity blast duration can be lengthened by performing chain attacks.
* While unable to use other blast types (I think they mean mirage blasts here), dumans can still utilize charge attacks.
* You can move about freely even after activating an infinity blast, allowing you to better position yourself for an ideal attack.
* So far, only the Hunter and Ranger infinity blasts have been shown officially, however Force and Vanguard blasts will be unveiled soon.
