it should be active skill like in warcraft mages can open portals for other people and portal them to specific area in this case aakman or other areas sage can go to, if u dont want to make it for other people fine make it only for sage, MAKE it active skill to open portal please, and give him some healing spells like wizard

Sage is an Engineer class. He has basically no relation to Elion. His ability to turn time is/was limited to himself by using the Origenus Kyve. At most it would make sense for him to be able to heal himself . 

Wizard / Lord Red were part of GodrAyed-Thea. Named after the God of destructive light and are masters of the elements. 

Valkyrie is part of elionism.

Shais are alchemists. 

That require development time, proper testing, so u wont land god knows where, etc, etc ,etc.

Knowing that PA, nowdays, recicle their content and just spam us with useless events....u gotta accept that.

Im on the same boat with u. I wanted to open a portal to Aakman, Histria,etc but u gotta understand how PA works when u see in patch notes:
- Fixed the abnormal position of Leila underwear for Dark Knight
.... Like who the fk care about that when we have so many huge ass problems in game right now.

Def doesn't need another healing skill, he's not Wiz/Witch and the three(hp) regen skills are enough. Have been for me in Sycraia and Orcs at least.

Portal would be nice, however a simple map transition to node would work fine. Shouldn't work for other players as this removes the uniqueness of the current rare portal team mates items.
