Strengths

 * Augmentation of all physical prowess, that is strength, speed, agility, endurance, reflex, etc by multiple times.
 * Flight at high speed.
 * Ability to suck away life force of any target provided Roson has caught it with his right hand. An extremely lethal ability as even the strongest individual will die if he/she is caught for 10 seconds. Cortez can activate this ability at will. only busoshoku haki can resist this ability to some extent if used as an armor.
 * Ability to resurrect dead bodies into ghouls much like Gekko Morai's Kage Kage no Mi, however these ghouls are much more brutal and cunning and is completely under Roson's command. Also the ghouls can strenghten themselves by cannibalizing each other, given enough opportunity to cannibalize, a ghoul's strength can rival a Supernova level pirate. The limit to how many ghouls there could be depends on the mastery over the fruit and as Cortez is very adept with his fruit, he can have a vast army of ghouls (no less than 200). The ghouls could not easily be killed as they are already dead, to stop them, their bodies must be incapacitated or purified. Haki attacks, seastone, or salt attacks can purify them however it's not as easy with the ghouls as it is with Moria's zombies because unlike the zombies ghouls are extremely cunning and crafty.
 * Ability to summon ghost like spirits, these spirits are like Perona's ghost but instead of making a person "negative" they make the victim go into an insane state attacking his/her own body in a masochistic frenzy ultimately committing suicide. Only individuals with haki can resist them. This ability can be broken by outside influence though.
 * Ability to regenerate at a rate faster than Marco can, making Cortez near invincible.
 * Last but not least, boosts the effect of haoshoku haki stronger (to the point where Cortez's haoshoku haki in Yama form is on par with Rayleigh or Shanks').

Weaknesses
No other weakness other than standard devil fruit weaknesses
