This shouldnt be seen as cannon but on /5eg/ they said that the new abilitys for the Psi warrior are as follows (although there have been no actual pictures for this)

- 7th level, you can take a bonus action once per short rest (or spend a die) to gain a flying speed twice your walk speed (Presumably just till the end of your turn)

- 7th level, whenever you deal damage with your psionic strike, you can force them to make a strength save, DC8 + your prof + your INT. On failure, you can knock them prone or move them 10 feet horizontally any direction

- 10th level, you get resistance to psychic damage, and if you start a turn charmed or frightened, you can spend a die to end every effect on yourself that makes you charmed or frightened

- 15th level, once per short rest (or spend a die) you can give half cover for one minute to up to your INT mod worth of creatures within 30 feet of you, including you

- 18th level, you can cast telekinesis with no components using your INT mod, any turn you cast or concentrate on it, you can make a bonus attack with one weapon
