Quick question...

Monsters in Anthara's lair:

Are any of them 100% resistant to sleep and root?

Pytan resist Sleep.
Pytan Knights don't resist Sleep.

You must have others that are immune to Sleep or Root.

I don't think any normal mob has a 100% resistance. You can sleep/root any mob, it will just take a few extra tries.

...so what is the final word?

Are there in C4 any normal monsters that are immune to sleep/root?

(I don't speak about raid bosses, cause i've seen them being totally immuned to those player skills)

No mob is 100% sleep-proof. You can sleep any mob if you have enough skill level, buffs and MAtk. I have slept every monster in Lair of Antharas, even though most sleep-resistant take too much mana on failed attempts.

100% sleep restance mobs are chest

100% sleep restance mobs are chest

I am pretty sure I slept one (only "pretty sure" because immediately after the sleep landed, somebody started attacking it... but I am sure I saw the "sleep ball" above the chest). But they are insanely resistant to sleep.

mimmics you cant

you can't sleep treasure boxes but u can sleep the chests

u cant sleep antharas :p

u cant sleep antharas :p

Rad mobs are out of question :) You can root them, sleep them or paralise them.

mimmics you cant

Just remembered this thread today when we were in lair and slept a chest. So, just to confirm: you cannot sleep the chests which give loot (the previous "boxes") - they simply disappear. But you can sleep the chest MOBS, i.e. the mimics. Just a quick pic here, (http://img140.imageshack.us/img140/7659/chestsleep9ao.jpg) because many people do not believe me you can sleep them (they are insanely sleep resistant).
