Same as 5eYou already know this as 5e Blade Barrier — It's Blade Barrier reskinned as Force energy — same 6th level, same 100ft×20ft×5ft wall, same three-quarters cover and difficult terrain, same Dex save for 6d10 (just force damage instead of slashing).
Conjure a 100-foot Force wall or ring: difficult terrain and 3/4 cover; 6d10 force (Dex half) to creatures entering or starting turns in it.

You conjure an immense manifestation of destructive light side Force energy. The wall appears within range and lasts for the duration. You can make a straight wall up to 100 feet long, 20 feet high, and 5 feet thick, or a ringed wall up to 60 feet in diameter, 20 feet high, and 5 feet thick. The wall provides three-quarters cover and its space is difficult terrain.

When a creature enters the wall's area for the first time on a turn or starts its turn there, it must make a Dexterity saving throw. On a failed save, the creature takes 6d10 force damage, or half as much on a success.
