Rena
From Portals of Phereon Wiki
Unique Beast Taur. Rena can be found through snow tile events. Her events consist of gifting the party a rare item. After several gifts, Rena proclaims she is out of things to give and you can choose to recruit her.
Despite being a Beast Taur Rena isn't very suited for frontline combat and fills a more supporting role. However her great speed can be used to power through unfavorable terrain in battle.
If you raise her level to 10 and make her a futa, it can trigger an event at the Town Beach. Choosing "handjob" will increase her energy/regen by 3 and teach her Invigorate, while choosing "calm" will raise her LRes by 3 and teach her Calm.
