This is a little tricky. I'd set up my Wizard so he'd be able to use a burning cone attack on some sentient trees next turn. Got the facing right and everything. Then another tree off to the side hit him with Entangling Roots, causing Halt, which prevents you from playing any movement cards. And, at least for now, prevents changing your facing when using cone attacks. Well, that's just fine, since my Wizard was already facing the right direction! Except . . . my Wizard had automatically turned to face the attacker off to the side. He couldn't turn back. Note that sequence: hit with card, card attached to Wizard, Wizard turned to face attacker, now Wizard can't turn to play a cone attack. We already knew that Halt, Encumber, and related things need review, but dang, it's like Entangling Roots has an identity crisis: "Sorry, my existence means you can't move anymore. By the way, you have to move now." The fact that these card rules apply to cards (i.e., you playing a movement card), instead of concepts (i.e., your character moving) is leading to some cruel effects that players really won't find intuitive.
Hm, maybe halt should stop the rotating towards attacker to happen - or maybe it would hurt in other cases where you'd actually want to reciprocate towards the attacker and couldn't due to this? Maybe halt could allow movement cards to shift facing at least - like encumberance?
Whether the devs want to allow us to change facing while Halted is up for them to say, but it's currently a mixed deal: you already CAN change facing by playing any other attack whatsoever (you'll turn toward your target). One simple thing would be to stop Entangling Roots itself from causing you to rotate. But it would be weird to make an exception for just a few cards. I hope they revise the "Halt prevents you from changing your facing when using cone attacks" deal to bring it more in line with other attacks.
Maze already has Stealthy keyword that does exactly this. So the devs could just add Stealthy to Entangling Roots.
Yes, I know. I was going to put that in my initial post; but like I said, it's weird to grant this exception to Entangling Roots without good reason. Maze, of course, has a good reason. On a related matter, the Stealthy keyword is still kinda an odd one: it's used only once in the entire game, so far as I can tell. There may be other cards that don't change your facing, but they don't use this term; and then the fun word "stealth" is used tragically little.
