What's The Most Efficient Way To Level Up A Vauban?

[OldGodKing]

Before anyone says it, yes I know that Infested Dark Sectors are the way to go, especially for Vauban.

But for a Vauban that isn't properly modded and can't spam Vortex or Bastille yet, he isn't really useful until I install the right mods on him.

 

I have the proper weapons to bring along while trying to level him up but he is extremely squishy and vulnerable against any factions other than the Infested.

You just gotta leech for a bit on Sechura, Pluto.

 

Usually, there always is another Vauban playing there, so just hop on a crate and let him do the work. Out of courtesy, let him/her know that you're trying to level up and that you won't be very effective.

ODD. stand on a post. ogris happy. put energy siphon and one full power mod and spam it.

The first thing I did when I got him was install Energy Siphoon, Fleeting Expertise 4, Streamline Max, and went on Apollodorus throwing my zap-zap balls everywhere.

Sechura on Pluto, Vorte spam. If you are not modded enough to spam Vortex - spam Teslas. They deal some damage, and the XP you gain is based on it.
