E: Rechargeable smokes which is similar to brims smokes i. e.., cannot smoke universally like omen or astra, you have to be close to the place you want to smoke.
C: can smoke after you die, but smoke placement is limited to small radius around where u die.That is you cannot die in b site and smoke for your teammates in A site. It looks like it can be activated only if you get a kill given that she keeps randomly tapping in the air after getting a kill in the trailer.
Q: Throw a small bubble which bounces of a surface and expands into a big transparent bubble which pushes out enemies inside the bubble radius.Works similar to fades seize but rather than trapping you it pushes you away and debuffs you for a short time.
X: Self revive which works similar to Reyna dismiss which means she is intangible for a few seconds which can help her to reposition to a safer place. Probably doesn't work if you're the last one dying.
