Sigil Enemies "Buff - Barrier" Intended Effect?

Just wanted to check if the “buff - barrier” is having the intended effect right now in sigils.

Like the other enemy buffs, this one gets reapplied as soon as it drops off. Problem is that barrier drops off once you’ve chewed through the barrier, and gets reapplied right back at full strength.

I wasn’t having trouble with this on normal enemies as I did enough damage to eat the barrier AND all their remaining health. Now I’m fighting a mimic and it’s… painful. Takes me a few turns to eat the barrier, I do a tiny amount of damage to its actual health and then the barrier goes right back up again.

Not intended, thanks for the information!
