This build focuses on sustain to keep you alive against enemy flanks and damages, so that you can continue to do your job (zoning out areas, pressuring tanks, farming Ult charge)
You can use Just Believe III instead of Twilight III if you want to.
- Start Haven if there are enemy DPS that you have an unfavorable matchup against.
- Wrecker if the opponent has shields. If they don't and you're free to damage them, then Morale Boost.
- Willo has Dead Zone so she doesn't always have to buy Cauterize, but she can Caut if your team needs it.
- Resilience, if you're getting CC'd
