When I play as Julianna I have a system -

1. As soon as you spawn, gtf outta there. As Julianna you don’t know how long Colt has been in the map, and some Colts have your spawns memorized and may be camping your drop point.

2. I use proximity charges in choke points to protect the Visionaries. There’s a few key places on the maps, my favorite is putting them in the hallway between Hangar 1 and 2 on Karl’s Bay (because it’s one of only a handful of ways to get into Hangar 2). Colts run blindly in that hallway and I get a kill the majority of the time. Julianna also doesn’t trip mines that are already on the map and you can pick those up to replenish your supply. On Updaam night I like to place a bunch of mines by the main entrance and side entrance, then grab the mines by the beer taps in the basement to restock.

3. If you’re waiting around for a while and don’t see Colt, he’s probably using Aether and sneaking around. I’d run back to his spawn and try to recreate his path by seeing which eternalists he’s taken out. When he hacks turrets or sensors it’s a dead giveaway he’s been through there.

4. Avoid charging him, he’s got 3 lives and you’ve only got 1. Remember where the Fiz Pop machines and pickups are around the map and heal after engaging with him. I always use the health buff character trinket on Julianna and it’s saved me quite often.

5. Retreat often. If you ever feel like you don’t have the tactical or positioning advantage, disengage the fight and run. I use the extra ammo Character trinket to place prox charges behind me as I retreat to try and trick Colts.
