Intimidation not working properly.
 

Intimidation is completely bugged at the moment, or there was a huge stealth nerf to it. First, it NEVER lands anymore. I have yet to fear an enemy with it at all. Second, it now breaks both sneak and hide. A week ago, I was able to sneak+hide up to a mob, attempt multiple intimidations behind it, fear it, and run after it while backstabbing. Now, I sneak+hide up to the mob, intimidate fails, I am no longer sneaking or hiding, and the mob attacks. Then, while attacking the mob, intimidate never lands.

Please look into this. This was a huge strategy for me to solo hunt as a rogue and made the game quite fun. Now, it's impossible to use this strategy.

Thanks.

EDIT: Also, I've noticed that when I press intimidate, the game will often not even let me know if I was successful or not. I get nothing except the character animation.

Must be placebo. Just logged in my level 35 rogue to test and landed an Intimidation on the first dark blue (lvl 32 mob) that I fought.
If the game isn't letting you know that 'you're not scaring anybody' its more than likely your hotkey itself is bugged and you should make sure to remake an intimidation button from your action window (Ctrl+C).

PS- if your skill isn't near the cap for your level, it will be less effective than the latter. Low skill intim feels like absolute horse shit, but when its capped for the level it feels genuinely good in my experience.

Okay, so I have done a bit of experimentation since my post. It appears that the bug ONLY occurs when I wear either my haze panther boots or my haze panther gloves. I know, sounds weird, but it's true. I can land an intimidate routinely with all my other gear equipped. I will not be taken out of stealth either. As soon as I equip either my haze panther boots or gloves, the bug happens. This makes sense because I just recently bought both items and haven't leveled with them yet, which explains why I didn't have issues just last week.

My skill is 200. I use it ALL the time. It's actually very effective for leveling up solo as a rogue.

I'm going to use your suggestion and try to remake an intimidation hotkey and equip the haze panther boots and gloves to see if that fixes the issue. I'll follow up with my experiment.

EDIT: Same result after making a new hotkey. When I equip either of the two items mentioned, I will ONLY get a result that indicates I failed to scare anyone. It appears that if I were to be successful, the game doesn't indicate it and the mob isn't feared. My character still does the animation, and the hotkey is on cooldown. I unequipped both items and the skill is working as intended. After experimenting and killing several mobs, I am confident that equipping either the haze panther gloves or the haze panther boots bugs the skill out.

Success for intimidate will give a kick attack. Are you seeing the kick attack in your log?

Does the kick miss?

Haze Panther Boots are not a magic item. Are you fighting something that requires magic items or immune to fear?

Not disagreeing with you, but I don't believe I have ever seen a kick attack animation when I use intimidate. I'll look closely here in a few minutes.

My experiments have been on spectres. I use the fear/backstab/snare trick to kill them pretty effectively.

Looks like we have a winner. Intimidate is, at least for rogues, a kick. If the mob is immune to your boots because they're not magical, you won't fear the mob. Pretty odd, actually. Anyways, that answers that. I'm not sure why the gloves are also the same, but I'm done testing. If you want to intimidate, at least if you're a rogue, be sure to wear magical boots when fighting undead.

I appreciate the testing by OP and deduction from samoht to get to the source of this. I have no idea if classic, but crowd sourced for the win

aye, intimidation always results in a kick (for monks and bards too im fairly sure) you just don't notice a kick on monks because... well.. .they kick

nice catch btw samoht
