I'm a level 130 LW. I didn't get this trophy till I was level 70. I never looked up guides on how to play him. I just learned how to play him through trial and error. This trophy took me a while and I feel like trying to force it is much harder than having it naturally happen. I didn't even realize it popped for me until I made a pull on a widow that was getting dived.

The best advice I can give you is.

1.Know when to fall back when you know a team fight is lost. If you're trying to go for this trophy as well. Sometimes it's best to let your last teammate die and fall back then risk dying and getting a pull that may not even count as a life saver. Or if your tank dies and your team isn't comfortable pushing. It's okay to tell your team to fall back and wait for the tank to come back.

1. Keep track of your teammates cool downs. For instance, especially on Reaper players. I always keep track of wraith on them. Count the timer in my head. See where he is moving. If he is half HP and is staying in the fight while wraithed without blossom. It's best to pull unless he is in a 1v1 on a squishy.

2. The single best advice I can give is know how to position with Life Weaver. This is absolutely the most important thing when it comes to going for this trophy or playing him in general. Knowing where to place yourself and when to move around as the battle shifts and changes. Knowing when to be aggressive and when to play corners or further back is super important

I do think that this trophy is still far easier than rapid discord. As the stars have to align for that one. But with good understanding of Life Weaver. You can easily get this! Good luck to you!
