How to properly use /tar ??

[Jimjam]

You need to make sure the NPC is within /target range

Replace spaces with underscores. You can truncate.

/tar an_an

would target an ancient cyclops.

Beware that if you mistype the name, or a name that doesn't have a target in range, you will likely bug out your target window and need to clear target (escape) for it to start working again.

A failed /tar could make you miss out on a bunch of attacks or spells if you are not careful.
