Time Wall blocks Stalker's Mark projectile, but still hits a target

[intricate]

Paradox places Time Wall, an enemy Drifter looks at Paradox through the Time Wall. From there Drifter casts Stalker's Mark. The Stalker's Mark animation is blocked by the Time Wall, however the Paradox is still hit by Stalker's Mark

Time wall doesnt blocks projectiles it slows them down

This is how Time Wall works with all projectiles, it doesn't block them. It simply stops them briefly so you can get out of the way.
