SolvedHelp for making bot in Grimoire 3.8

Is there a command for Grimoire so that it can change classes This is becuase I keep getting stuck when farming DCS in escherion and his staff of inversion.

There is no such a function in Grimoire 3.8. Why don't you request it for the upcoming 4.0 version?

EDIT
I'm sorry I was so blind, thanks to @KekkeTex for enlighting me. I really though that it was removed in the current version.

There actually is.
In the item menu, open the first dropdown menu and choose "Equip item"
In the box below you write the class name. And then click "add command"

You have to keep in mind that both will use the same skill combo though. So certain class combinations might not work well.
Previously you could solve this with a Load bot command to switch to another bot automatically with different skills. But it's bugged in 3.8.

You can still use the Load bot command in Grimoire 3.8, you just need to put the bot files you will use in the root of the Grimoire folder, or double click the command and change the:
"BotFileName": "example.gbot"
to
"BotFileName": "Bots/example.gbot"

If you want it to open the ones inside the bots folder.

@gaffox Sweet, thanks for that.
