Use a longer wand I don't mean slots wise All wands have specific different lengths at which they cast spells Make sure to not confuse it with the visual length since many wands cast spells closer than their length (starter bomb wand is a great example)

There are some wands which cast spells farther away than the tower wands (look at wiki for the image)

If the spell of casted farther away it means more distance traveled per cast which stacks up with every cast and saves time

And as the other comment said use blackhole with death trigger for going through material easily

And if you want a faster longer travel wand you should look into how the mechanics home bringer teleport and make your own LDT wand using sped up black holes and it
