(Seemed better than "situational awareness", plus it went better with the insult about not being able to read. I guess I got a little carried away. :D I'll leave it like that.)

(no prob, was just curious!)

(That's a very creative way to deal with the witch and minimize violence. And if it fails, we can always go all-in with everything we have).

( Your character hasn't even seen the paintings yet, so he can't really think about any strategy with them.
I like ZyloxDragon's (Roy) idea to drop a painting on the witch and then destroy it to prevent her return.
Maybe he'd need an intelligence check for such plan tho.. )

(Well obviously once he comes to and sees the paintings, he can formulate that plan. I do like just dropping the painting on the witch the best. If it can be removed and lifted then I'd say to try that first.)

( He's stunned on the ground, with an evil witch in front of him, and he has time to recover, enter a room (for what reason?), observe the paintings, realize that they're portals and then formulate a plan? I'm not sure about this..
Anyway yeah, I see the painting's strategy as the only winning one, if it's possible. )

(True, I'm not sure Benkii character knows already about the paiting)
(Also, just as a recap, Peloquin is already working on a painting for the puprose of catching the hag)

There's no guarantee that these painting are 2-way doors. For all we know, even touching the frame might suck one of us into the painting without a visible way of getting out (from the inside). It would be best to have test subject.

However, it's the heat of battle, and the paladins have caused chaos, death and destruction (even though orcs are generally blamed for these types of things). Roy will be heroic, and try removing whichever painting he is closest to, and see if he can get the painting "onto" the hag. First cast Reflect Spells on himself to "possibly" mitigate any effect touching the painting does to him.

Current Actions Summary:

40 - Pouyou-pouyou - Gilius - Dwarven Druid
I order the stone elemental to get close with the hag, and grab it with its arms to hinder her from moving and doing
anything. If possible, I order it to try a headbutt on the hag to stun her.
Meanwhile, I go to BenKii and I help him to regain his senses and get on his feet. "Congrats, lad ! Now is your time to play hero ! :D"
I help him to stand up and push him to fight the hag.

25 - BenKii - BenKii - Human Warrior -- STUNNED
In case I become unstunned before the end of the turn, I get up and try to attack the witch that came out of the right door.

13 - paladin181 - Roosevelt - Human Paladin -- STUNNED
++ROOSEVELT REGAINS HIS FEET AND MOVES INTO POSITION NEAR THE HAG, READY TO PUSH HER WITH HIS SHIELD BACK THROUGH THE DOORWAY++

67 - Testor0 - Rufus - Human Cleric
Disturbed by the paintings: "I really don't like those moving arts, another curse on us! There might be a connection between the painting world and our."
Rufus asks his guardian to take the lead in the left room and walk just behind him, still protected by the Globe of protection.
Seeing the flying movement in a painting, Rufus goes to that painting.
"This! Look! It's comming! It's a bird ! Or maybe it's a Supernightmare! ...for sure a new threat to our group! I'll stop it
RIGHT NOW!"
If the painting is easily flammable Rufus burns it with his torch. If not Rufus wraps the painting with his net in order to
trap anything that would liike to come out of it.
"Could someone trap the other painting?"
Rufus and his guardian stay alerted of any living movement from the other painting and any movement in the room.
Do we see anything new in the room?

68 - matterbandit - Peloquin - Dwarven Thief
1.I make a quick entrance into the Left Room, shutting the door behind me, in the hopes the Hag did not notice. My mates can open it if they want in. I step ahead of Rufus, but behind His Guardian, so that I may inspect the room for traps and disarm them if I find any. I glance up at the ceiling too, in case one of the Hag sisters lurks there. I ready my Light Hammer and my Ring Of Free Movement.
2.I inspect the painting on the left, the one with a desolate mountain pass, a rope bridge swaying gently in the wind. Is it a trap? If so, can it be disarmed? Is there anything else of interest inside the painting? If things can come out, can things go into the painting? Can I remove it from the wall? I wonder how the three paintings are linked? Maybe we can use it to lure the Hag into this desolate mountain pass?
3.I turn to Rufus: "What if we held this desolate painting in front of the other to catch that flying creature? Would that
work?"

63 - Genocide2099 - Fish - Half Orc Berserker
Foolish humans! Always thinking with the heads between their legs! If that stone monstrosity is able to hold down the hag's arms, I'll quickly climb up it's stony back and bring down my axe on the hag's skull. I have the same plan if it manages to stun the hag. I am hoping that the stone monster can protect me while I attempt to kill the "helpless damsel".

38 - ZyloxDragon - Roy Jenks - Half-Orc Battemage
How big are the paintings on the wall? Small enough to lift off the wall and move around without much of an issue, but large enough to completely encompass a person? If something can go back and forth between this world and those worlds, I can see using these as makeshift weapons. Just toss the picture over a creature, and lit it sit facing down on the ground. Let physics do the work of keeping it in there.

57 - ConsulCaesar - Siegfried - Human Paladin
If Tanea is not able to bring BenKii and Roosevelt back to consciousness, I use Heal on them.
If the witch is still alive, I attack her with my silver sword.
After (if) everything is cleanes up, I walk into the left room.

58 - FlockeSchnee - Tanea - Halfling Shaman
If the Hag can be made to fall sleep or get entagled (which she probably won't), Tanea will cast either spell. Otherwise she will cast "Protection From Elements" on Siegfried, just in case.
The Ice Elemental positions himself close to the wall in which the door was, hopefully out of (at least immediate) sight of the Hag. If she steps out and gets engaged by the Ghast/Stone Elemental and/or others and his action wouldn't hinder those already "on her", he will try to hit her on the head (from above striking down, _not_ to the side; wouldn't want to accidentaly knock her loose again, if she happened to be in a firm grip already)
Tanea goes to check on BenKii and Roosevelt, if either or both of them require/s healing (and Gilius hasn't already taken care of that), she casts Heal on them (Roosevelt first, because Gilius is with BenKii).

74 - runnerex - Yeenwi - Drow Necromancer
Yeenwi mentally commands the two Ghasts to flank and attack the Hag and to also try to avoid biting anyone else.
Then Yeenwi shouts at the Hag: "Oh, great Witch, forgive the insolence of these fools. An all-powerful magical being has summoned us and ordered us to find the most worthy of magical wielders. It wants to impart its wisdom, but only to someone deserving. As you can see by the actions of the rabble around, they were not deemed suitable and I was lumped together with them. The path to the being is down this tunnel and then into a metal grate. You might want to hurry, because there are several other parties also looking for candidates. Of course, you can engage in battle here with the fools around you, but then you probably won't get there in time. Just think how much more powerful than your sisters you'd become..."

Haven't taken turn yet:

45 - phaolo - Loradan - Elven Mage
76 - Lemon_Curry - Shins A'Hoy - Halfling Thief
4 - sasuke12 - Strigon - Drow Necromancer

The sudden explosion made Loradan startle and retreat a few meters.
Those fools! I tried to warn them! - he thought, seeing the two humans stunned on the ground.
Then, an horrible creature emerged from the blasted doorway.. it was a Hag, a powerful witch!

His options against such magic-resistant foe were limited.. again.
But fortunately, some warriors were ready to react and they immediately attacked the monster.

Loradan, however, tried casting Dispel Magic on the Hag, hoping to weaken her magic protections.

I, Strigon, drow necromancer casts death armor upon me to protect myself from any magic attacks by the Hag.
I, Strigon contemplate whether it will be better to just shut the door on the left and have it locked and barricaded to make sure whatever is coming out from the paintings cannot come out of the room.

It would be a shame if the creature coming out of the paintings was friendly and wanted to attack the Hag in our defence.

Fish the Half-Orc Berserker

My fellow orc just gave me an idea. We could try going inside the right painting. The one with the tress and tall grass. Even if the hag can follow, at least we have a more open space to fight. I miss the sun and open air. Being inside this tunnel is making my blood boil.

Too dangerous : we have no guarantee that this will not be a 1-way trip. And we're not even sure that we can "enter" a painting. Maybe it's just possible to come out of it.
If it's possible to come in and out, and if we want to get rid of the flying creature in the center painting, we could just put one of the side paintings in front of the center one, facing it. Whatever comes out of it will instantly come into the other one without harming us.

I kinda favor the lure the hag into one of the painting world strategy. Of course, we have so many other ideas that could work, so updated actions:

If Tanea is not able to bring BenKii and Roosevelt back to consciousness, I use Heal on them.

If the witch is still alive after creatures/elementals/spells are being thrown at her, I try to lure her into the paintings. If this is not possible (e.g. she is immobilized or the door to the left room is closed) and/or she becomes aggresive, I attack her with my silver sword before she attempts to hurt anyone.

After (if) everything is cleaned up, I walk and join the rest of the group in the left room.
