Leaga's You're a wizard, Seven.

Try to keep to this order except buy Healing Rite when you need.

QSR on 3 is safe
On 1 is better
Everything else in build on 1

Ult in enclosed spaces with the team if doing Hunter's Aura
Reverb to make 1 BIG

Components in next box or earlier in build
Kevlar if people focus you in ult

All 4 above in a finished build unlikely

If you want to upgrade some of those early slots

when you feel like it.
