Guide
MOBBING BUILD
Spam her 1 and 2 for movement and damage. Use her 3 to group enemies, then hit the ball twice for AoE. Use her 4 against tougher enemies.
Bio Expansion/Spear and Shield can be used if you don't want to proc Hyperfocus.
BOSSING BUILD
Use her 1 to build Charge, then use her 3 followed by her 2. Use your 4, then spam 1 and 3 until the cooldowns on 2 and 4 are over. Repeat until the boss is dead.
Power Beyond can be replaced with Ice Breaker if you take too long to kill a Colossus, but with Dia, chances are it'll die in seconds.
BOTH BUILDS
The only difference between the two is that we don't need Range on the Bossing build. The Reactor is also different, but you can use CHD/CDR for both.
The most important stat on the Ancestor Module is CHC. Dia needs 400% total CHC to reach the cap when not using a melee weapon.
You can replace Chill Integration with Front Lines and/or Hyperfocus/Spear and Shield with Emergency Measures to reach it, or use them if you don't have an Ancestor Module at all.
Hypernova can be used to proc Hyperfocus by throwing it. It even rhymes.
