Round 3
Amaryllis, seeing no way she can do as Seebor suggests right now, either
(a) slinks back to the wall, desparate to get some distance between her and the earth elemental. The move it to square A4 [I think this is not possible given the 50% thing but as I am small, I thought I might have some advantage over medium things]; or
(b) positions herself between A4 and B4 and behind the door such that F doesn't get an extra attack [can I do this?]
(c) steps back to A5 [again, not sure if possible]
To Seebor, she says cynically - "Good idea but maybe later"
Assuming that magic missiles are of no effect, she draws her wand of burning hands, and casts hoping that a different element might be of more effect (after all, she did hear the word elemental mentioned - loose associations are about all she can manage being adjacent to a dangerous looking thing that she has never seen before). [If damage is done, it is 1, 4, 1, 2, 3 = 11 or reflex save for half damage; if anything is made of "thin wood" within 10 feet, it burns; Seebor, being 15 feet away, is safe]
[OOC - Sorry about the question but I thought my knowledge check was for recognition on sight as opposed to knowing anything about earth elementals once named; am happy to let the roll cover both.].
If there is no position to which Amaryllis can move without provoking an attack, Amaryllis draws her dagger, screams, and goes on full defense.
