 ### Far Wand
-The far wand (`worldeditadditions:farwand`) is a variant on the traditional WorldEdit wand (`worldedit:wand`).

 It functions very similarly to the regular WorldEdit wand, except that it has a _much_ longer range - which can be very useful for working on large-scale terrain for example. It also comes with an associated command to control it.
 
+Note that punching out the positions **does not unset them**. Use `//reset` to reset the defined region.

 Unlike the other 2 wands, this wand functions in an additive manner. Left-click on a node to expand the currently defined region (creating a new one if one isn't defined already) to include that node. Right click to clear the currently defined region.
 
 It has the range of the _Far Wand_ mentioned above too, so you can select nodes from a great distance. It also abides by preferences set via the `//farwand` chat command.

+### Multi-Point Wand
+The third type of wand provided by WorldEditAdditions is completely different, in that it allows you to select up to **999 points** at once!

+It is important to note that (at present) the points selected by this wand **are not compatible with normal points**. This will change in the future, but requires a lot of work to implement.
