Is it okay up to level 2-4? Or does it also get ruined?

all effects of dynasty weapons work up to and including the fourth level.

I leveled up the Tide Staff myself, and its barrier worked, but honestly, I'm too lazy to check now if this ability has disappeared.

I leveled it up to the fourth level myself, but I was too lazy to level up the fifth.

How will it throw it out??? The Iron Quill is currently being leveled up, and I've already played several battles with it - it's intact, in place, and the timer is ticking.

damn, when I was leveling up one of the artifacts and started playing with it in the game, it stopped leveling up in the Forge; it seems they removed this possibility.

PS: citizens, those who know foreign languages, write a complaint to Ubisoft about this bug with leveling up to the fifth level.
