Construction Wand

With a Construction Wand you can place multiple blocks (up to 1024) at once, extending your build on the side you're facing. If that's not enough: you can upgrade your wand with additional cores, allowing you to place a block behind the block you are facing, conjure blocks in mid air or destroy lots of blocks very fast.

Note: These are the instructions for ConstructionWand version 2.0+, which introduced some new features. If you are still using version 1.x, refer to those instructions.

Wands

There are basic wands made from stone, iron and diamond and the Infinity wand. Wands from higher tiers are more powerful and last longer. These properties can be changed in the config.

Wand	Durability	Max. Blocks	Upgradeable	Angel distance	Max. Blocks (Destroy)
Stone	131	9	No	-	-
Iron	250	27	Yes	1	9
Diamond	1561	128	Yes	4	25
Infinity	Unbreakable	1024	Yes	8	81

Crafting

OPTKEY

To change a wand's core and options or undo your placement you need to hold down the wand option key (refered as OPTKEY). By default, this is CTRL, but it can be changed in the client config file. To prevent unwanted changes to your options, you can configure that you have to hold down SNEAK as well to change options or open up the GUI.

Wand cores

Wand cores are magical gemstones that make your wand do its thing.

Every wand comes with a Construction core. You can make your wand even better by putting aditional cores into it. Put your new core together with your wand in a crafting grid to install it. To switch between cores, hold down OPTKEY and left click empty space with your wand. Stone wands can't be upgraded.

Construction core

Extend your build on the side facing you. Maximum number of blocks depends on wand tier. Hold down OPTKEY and scroll to change placement restriction (Horizontal, Vertical, North/South, East/West, No lock).

Angel core

Place a block on the opposite side of the block (or row of blocks) you are facing. Maximum distance depends on wand tier. Right click empty space to place a block in midair (similar to angel blocks, hence the name). To do that, you'll need to have the block you want to place in your offhand. You can't place a block in midair if you've fallen more than 10 blocks deep (no easy rescue tool from falling into the void).

Destruction core

Destroy blocks (no tile entities) on the side facing you. Maximum number of blocks depends on wand tier. Restrictions work just like with the Construction core. Destroyed blocks disappear into the void, you can use the undo feature if you've made a mistake.

Options

SNEAK+OPTKEY+Right clicking empty space opens the option screen of your wand.

Restriction: If restriction is enabled the wand will only place blocks in one row or column (choose between North/South, East/West on a horizontal plane and Horizontal, Vertical on a vertical plane). If the direction lock is switched off, the wand will extend the entire face of the building it's pointed at. This option has no effect in Angel mode.

Direction: If set to "Player" the wand places blocks in the same direction as if they were placed by yourself. Target mode places the blocks in the same direction as their supporting block. See the picture below:

Replacement: Enables/disables the replacement of replaceable blocks (Fluids, snow, tallgrass).

Matching: Select which blocks are extended by the wand. If set to "EXACT" it will only extend blocks that are exactly the same as the selected block.
"SIMILAR" will treat similar blocks equally (e.g. extend dirt and grass blocks).
"ANY" will extend any block on the face of the building you're looking at.

Random: If random mode is enabled, the wand places random blocks from your hotbar.

Undo

Holding down SHIFT+CTRL while looking at a blocks will show you the last blocks you placed with a green border around them. SHIFT+CTRL+Right clickking any of them will undo the operation, giving you all the items back. If you used the Destruction core, it will restore the blocks.

Additional features

If you have shulker boxes in your inventory filled with blocks, the wand can pull them out and place them
Botania compatibility: The Black Hole Talisman can supply blocks just like shulker boxes can. Having a Rod of the Lands / Rod of the Depths in your inventory will provide you with infinite dirt/cobble at the cost of Mana.
Having blocks in your offhand will place them instead of the block you're looking at
Look at your statisics to see how many blocks you have placed using your wand
1.16+ only: The Infinity Wand won't burn in lava just like netherite gear.

TileEntity Blacklist

Some modded TileEntitys can cause issues when placed using a wand. They may turn into invisible and unremovable ghost blocks, become unbreakable or cause other unwanted effects.

That's why I've included a Black/Whitelist system for TileEntities in CW Version 1.7. Chisels&Bits blocks are blacklisted by default. There are probably a few other tile entities from other mods out there which may cause issues as well. If you find some of them you can tell me by creating an issue, commenting on Curse or editing the default blacklist yourself (it is located at https://github.com/Theta-Dev/ConstructionWand/blob/1.16.2/src/main/java/thetadev/constructionwand/basics/ConfigServer.java#L28) and making a PR.
