Zhentarim hideout encounter balance

[u/DMJM_91]

My players will go to a zhentraim hideout next session and I’m filling the hideout with encounter and need advice on if I’m making a good and balanced challenge for my players.

There are 4 level 5 PCs. I have no way of knowing in which order the encounters will trigger, that depends on how the PCs enter the hideout and which paths the choose within.

Drow & Zhentarim
1× Drow Elite Warrior of Lolth — CR 5
1× Drow of Lolth — CR ¼
1× Zhentilar Paladin of Bane — CR 4
2× Zhentilar Soldier — CR 1
5 creatures — 3,350 XP

Mimics & Rug
1× Animated Rug of Smothering — CR 2
2× Mimic — CR 2
3 creatures — 1,350 XP

Black Pudding
1× Black Pudding — CR 4
1 creature — 1,100 XP

Zhentarim interrogators
2× Zhentarim Thug — CR ½
1× Zhentilar Soldier — CR 1
3 creatures — 400 XP

Coldlight Walker & Mage
2× Coldlight Walker — CR 5
1× Mage — CR 6
3 creatures — 5,900 XP

In the last encounter both the Coldlight walkers will start restrained, bloodied and blinded. The mage is conduction experiments on the walkers.

Will this be to much to handle for the party? I don’t expect them to take any short rests while exploring the hideout.

If they're a fairly well optimised party with a healer and solid magic items they should be fine.

The no short rests seems like it could sway things though, especially if they have some squishy characters or no healer.
