Suggestion for in-game on how to combat botters!

[Neuflune]

They're actually not invisible - they're just hiding under the ground. It is possible to see their names if you target the enemy's target. Using the <tt> chat command while targetting the mob is also a good idea since it'll give you the name of the bot in the chat log. xD

I know about the underground bots.

The bots that I saw at Sagolii desert around the sundrakes area could not be targeted by the mob at all. I know how to use target-of-target, but it only works if the mob could actually target their attacker.

Edit: No, they were not ninjas. They were all thaumaturges using Fire 1 repeatedly just as the sundrakes spawned.
