This is really confusing. Really. I'll try to go point by point.
I understand that Teno contains the abilities that allowed him to dodge the earth pillars (both his sensing to detect them and his armor's jetpack to dodge them) however, I honestly can't understand the description. For you to have dodged using the Jetpack you should have either quoted the jetpack technique, explaining if you reactivate the jetpack or use the dodge or at least post the chakra count to make us able to know if you have used the 20 chakra cost flight or the 30 chakra cost dodge.
As for the rain and the clone. I don't know exactly if the clone can detonate to a degree of Mid-range (up to 15 meters all around) nor if it will detonate only when input is given for it to detonate or if hit. But even in either scenario, I believe the explosion needs to be short range of you for something to happen so I don't think its that much effective if it detonates between both opponents or at mid range of eachother. And if it was effective teno, you're also in the blast radius. Long Range-Mid Range-Short Range. You left the clone at mid range and moved back to long range...from your opponent, not your clone. If the clone has a mid range blast all around, you'd be caught in it as well.
Now, can the rain hit teno? Well, earth and rain are done at the same time but the rain is a bit slower to actually "happen" and reach the ground level. And its limited in range. Considering the jetpack, I think it can be feasible that teno escapes backwards in a nick of time.
My main issue is what teno used to dodge the pillars: free form flight or the dodge move. In the description, its not clear and it does actually seem to be understood that its a free form flight and not a dodge/dash as described in the armor.
Going back into long range, My sword quickly sense a pool of chakra from the ground, In quick haste Hakumen propels upwards, and right as the earth pillars would start to erupt He would release a burst of jetpack speed that propels me forward. At the same time as I propel forward, the wind shoots off from infront of my chest, Killing you and your clones. In the case the clouds have some acid rain falls on hakumen, He sends one of his orbs right above him to neutralize any acid that would come in contact with him as he released his wind jutsu. The wind jutsu would also cancel out your sulphur etc and the whole 9. (To be clear, I am now hovering over the open fissure) Once this is done, Everything infront of me is now erradicated
Also there is a slight inconsistency with Teno's description and timing.
Earth Fissure/Acid Rain
Moving Backwards/Blinding Light
Earth Pillars
Celestial Spheres
Sulphur broad attack
Wind technique
You only use the wind way after you've moved into long range. So there is a slightly weird wording/timing there. However, the wording in Zanda's move also bugs me a bit and I cant 100% understand all of it. The question also exists if being blind would prevent Zanda from performing his attack with such clarity. Because its beyond normal blindness as you see the world as an empty white void, clearly beyond the normal blindness we can achieve in other manners.
Now, using this time line, I propose the following:
-Teno counters the Rain with one Celestial Sphere, meaning only one is left, he is still mid range, the clone has exploded without hurting anyone
-All of Zandas technique happen and, in the case of the sulphur, they clash with the Wind. As wind is neutral to sulphur, 2 A-Rank Sulphur VS 1 Forbidden Rank Wind = weak S-Rank wind continuing towards Zanda
Its Zanda's move now, which needs to counter the weak S-Rank wind blast that is coming towards him (with some sulphur in between). In this move, Zanda and his clones are once again able to see in perfect clarity.
Small note though: please be careful with description. This judgment is based solely in an interpretation of what you guys wrote, not 100% what is written because what is written is very very cnfusing, specially and mainly, Teno's move.
