At 
Nex, it is incredibly important that she stays in the centre until pillars for a variety of reasons (You misclick or she gets 
voked (or you die and someone else needs to re-centre)). However, sometimes Nex may move from the centre and requires re-centering. In this case follow the steps below:
⬥ Stand in the middle of the arena
⬥ Voke if needed
⬥ 
or walk directly opposite of where she ends up standing
⬥ or walk back to the base spot
In the example image below, the X tiles represent the tiles where Nex will end up standing on after you voke her while standing in the centre. You should then move to the opposite X (so in the image, if Nex ends up standing on the yellow X, you should move to the blue X to re-centre her).
The reason it is important to move back to the original base spot after re-centering is that if you are standing on the red tiles before minions run into the middle, you risk blocking them. The green tiles are 'safe' tiles, on which you will not block minions when standing on them.
⬥ Should Nex move before the Elements special in Phase 1, do not re-centre her as she will re-centre herself when jumping up for the special attack. Instead make sure you have her aggro and that you are in the base spot.
⬥ Do not walk through Nex while re-centering her. This will cause her to move off centre.
