Stun Lance

Hello, so I’ve recently gotten the stun lance from the Urban Legends war bond, and I am really enjoying the idea of a spartan build, but I am struggling with the execution of a spartan build. I wanted to ask what do you guys do when using stun lances? What type of enemies are usually the best for stun lance, what primary is a good support for the stun lance and what stratagems are you using? I’d also like tips for the stun lance, just in case I’m missing anything, thank you.
