As Rhokkan lay twitching but not dead, Savlin finally manages to shake off the icy grip of fear, charging back in and drawing Bleeder, wishing he hadn't dropped his other sword in his original panic.
Darius steps forward and immunizes the familiar(gogo See invis.

) and it assaults the beast before stepping back, another blast of acid zooming in between the familiar and Darius as Carl blasts the creature yet again.
The beast seems to consider the situation for a moment. It appears badly wounded, and begins Concentrating.. When nothing happens, it growls in frustration, Pushing past the summoned Bearded Devil as it runs down the corridor, ignoring the Bearded Devil's clumsy attack.

Lucky you guys, it failed the Summoning Percentiles.
a few things of note.
[sblock=Walking Dad]You just happened to use the ability that it isn't resistant against, which seemed suspicious to me since your character is supposed to know nothing about it. As such, I asked WHY.
Your response would have been perfectly fine except for this:
Using your highest level power shouldn't need more explanation. Or do you ask wizards why they use acid arrow if they have magic missle avaiable?
Yes, actually, I do if their opponent happens to be strong against magic missile or weak against acid and they don't know that In Character. Especially since Magic Missile is usually a better choice, dealing more damage and auto-hitting. (Much like with your ability which was changed to a Fort Save vs a large, tough-looking creature, hence making me wonder 'why?') Either way though, it shouldn't matter. When asked a question by your DM, it's considered good manners to answer it without being snarky/disrespectful (Such was the tone I got from your response, whether it was intended or not). I'm not trying to say you're cheating or metagaming, just that when something pops up that makes me wonder why, I AM going to ask for, and expect, a reasonable answer. I expect this won't be the first time, and you won't be the only one to receive such a question, but if you take it personally, this won't be a fun campaign for either of us.[/sblock]
Secondly, Invocations are spell-like abilities that provoke attacks of opportunity, and the beast has 10' reach. I'm ruling that you noticed this (it did attack the troll from 10' away) and are casting defensively, so I'll roll the concentration check for you.
Concentration, DC 17 (1d20+19=36) Succeeds (didn't nat 1), so nothing changes. *EDIT: Actually should've been DC 18, the 17 was a typo, but it changes nothing*
Couple notes for ALL - When Moving, please post how far you move, so I don't have to check your character sheets for any movement effects you may have. (I checked this time, just keep in mind for future posting)
ALSO, I appreciate some you trying to lend a hand, but I'd much rather you at least PRETEND you don't know what the monster is. Unless you successfuly made the knowledge check (Which was only Albedo), your character has no idea what it is, and as such, I'd prefer ZERO metagaming (such as pointing out it's Resistances[Kinem], talking about/reading about it's AC, saves, or anything else like that). If your character doesn't know what the monster is, then try and ignore your OWN information about it (And please, if you don't allready know about it, don't go reading up on it till after the fight).
Bearded Devils AoO on the Ice Devil for rushing past:
AoO (1d20+13=14, 1d10+9=14) Nat 1.
