That, but steel axe/spear/pick and a bronze haft (presumably a two piece weapon riveted together, but I didn’t think ahead far enough to specify that in the sheet. The pick itself would be thinner and not conical like the above, more similar to the below picture). 

Sorry about the wait, but I wanted to be absolutely sure that I wasn't missing something so I went back over everything and ran it through on paper, in my head and irl a few times. 

I absolutely think Zande could get the weapon deflected off the line, he’s the physically superior opponent and besides, a hundred pound trained fighter can deflect a blow with a strike to the correct angle, but I'm a bit confused as to where you think the weapon is being deflected to. Directly stopping the blow from a standstill against a charging opponent seems unlikely to me, and I ran it through in a kata/scripted fight all Hollywood Dojo style earlier to make sure I wasn’t missing anything obvious, but if you think Zande could do it I'll totally give it to you. To my thinking it's a terrible position for him, though. 

My timeline is that Aibhilin moved toward him and covered the thirty feet or so, giving him ample time to draw and load his blowgun and the secondary pouch of venom (super cool idea by the way, I've never seen that in a fight before) before she could reach him. As she was still moving he turned and fired, the dart hitting the broadside of her halberd's axehead. She then stepped to the opposite direction he had turned (you said counter-clockwise, and he was facing away from her so I take that to mean left) to which she stepped opposite (now Aibhilin's right, his left) to put the maximum distance between herself and his dart gun while swinging with her polearm and, at this point she was most open to the spit attack which I'm assuming occurred simultaneously with her strike. If it did not he'd be spitting, not using a hose or water gun, spitting a little ball of liquid eight to six feet at best at an opponent who had not yet struck with her axe and would still have been holding it over her face and most of her eyes, head tucked and moving, which I consider to be an impossible hit. 

Assuming he spit as she stepped and began the slash he'd have to fire across his entire body or step to the side to square off with her (which if he's swinging with any intent with his right arm toward her blow I assume he would want to stay planted rather than try and step in time with his swing into a blow he didn't necessarily see coming). If that's all correct then her left eye would be mostly visible to his perspective, but if he's swinging right as she is swinging from his right (she is physically to his left side and forward of him, but the halberd is held at three quarters of the length in her left hand, thus the strike at a tucked elbow length would still be to his right traveling left). The problem is that if he is actually doing that while holding a blowgun at his mouth in his left hand and firing the spit attack to my thinking, and what seemed to be backed up when I ran through it is the deflection is actually sending her blade into Zande's left arm, currently crossed over his left side and gripping a blowgun at his mouth. 

There are two problems here. First Zande is traveling directly in front of his blowgun as it's pointed toward Aibhilin's face with his axe if he blocks from the right, which would absolutely mean the spit attack would land on Zande's right arm, axe, Aibhilin's weapon, her left arm, and helm with almost no chance of landing in her eyes through all the traffic (it's a little ball of venom after all, this isn't a fire hose that has equal water pressure over a large surface area) and in addition to this Zande is actually deflecting the blow into his own arm while holding a blowgun. This isn't a strong enough blow to do much to Zande’s steel mask beyond knocking some teeth out from the kinetic energy of the strike and maybe knock him on his butt, but to my thinking if that went into his forearm it would go through it, and then through the bicep behind it, and the fight would just be over. I can't see Zande making that choice. 

Otherwise he could loop under the blow and try to deflect it up, which would be a much longer journey then Aibhilin's straight lined slash and she has the advantage of proactively rather than re-actively striking or blocking, or loop up and then slash downward to try and tank it into his breastplate, the safest option I could see running through it but still a longer journey then her strike. The second issue I noticed is that because he pivots to fire, he’s almost certainly too planted to get off the line enough to entirely deflect the blow away from himself. Unless he pivoted and side stepped directly away from Aibhilin which wasn’t mentioned but is of course doable, in which case from his perspective he would now be facing her axe head or, if he really jumped backward, her spear point, both of which would be easily reacted to by her as she moved either into Zande’s right leaning momentum or completely (in the case of his having moved backwards entirely) geared toward a simple lunge/thrust and place Zande’s momentum either going into her strike or backward, which would mean that he’d now be facing down a spear point while going backwards and totally able to deflect it but not without being caught by the thick of the pick (or axe if she twisted the haft with the thrust in the Chinese fashion) while moving backward, almost certainly putting him on the ground and very open to a follow up. 

I mean, I’m just doing this for fun, so if you want to say the spit landed, or missed, and Zande deflected the blow and just reset from there I’m totally game for that, but in any realistic fighting sense I think turning your back on an opponent with a halberd who then runs at you and swings, to which you respond with spitting in their eyes through a blowgun while trying to deflect the blow from a standstill and toward a strike at the same level as your head (keeping in mind the strike, and your blowgun are both at Zande’s head level so there isn’t any difference in strike zone as there would be if you were striking at the shorter Aibhilin’s head or she was firing and holding the blowgun) is a zero chance of survival situation. Mostly I just wouldn’t turn my back on someone with a halberd, but again, I’m doing this for fun. If you want to say Zande legitimately sidestepped while firing and blocking against a strike whose angle he couldn’t have predicted and reacted to quickly enough to outpace a proactive and aggressing opponent all accurately and simultaneously I’d just as happily go from there, especially because otherwise I think the fight is going to end quickly and who wants that? I’m here to cross some blades and bleed while making him bleed after all. If I’m missing something by all means let me know, but I ran it out a few times and I’m pretty sure it’s just an unwinnable position except through the acceptance of it just went good for Zande through a turn of fate type of deal, which I am open to and highly recommend. 

Just let me know where you want them positioned and whether the spit hit or missed, and if the halberd was deflected and in what direction relative to Aibhilin's position when we pick it back up.
