Be silent no longer,
For even their screams will be drowned out.
By our voiceless cries,
By our inescapable dominion,
They will melt into an oblivion of our design.

5 Tauforged Topaz shards - Gain Health via Blast
Allows for nearly 3k Health and result in over 470% Ability Strength
1 shard can be replaced with a Tauforged Amber Casting speed if preferred, but will lose out on some Ability Strength, though only a somewhat negligible 6-10% due to the final shard only filling the final 329 health required for Arcane Bellicose

We forego all Ability Duration in favor of Ability Strength and Range while upkeeping a nice Ability Efficiency as the playstyle is purely dependant on single-cost abilities
This build is quite expensive but is designed to throw out crowd-culling and gathering abilities at great values

IF YOU WANT MORE RANGE, SWAP OUT Stretch FOR Overextended

This will, however, require you to use an Umbra Forma instead of (let's say) Stretch's Naramon polarity
My recommendation is to forma 1 Umbra and skip Stretch's Naramon so you can switch it out for Overextended as you please

This build is quite versatile in terms of ability usage but essentially boils down to a favored order of
1. Airburst for a fast and simple gathering crowd control
2. Sonic Boom to quickly [Shred] the dogpile's armor
3. Sound Quake for our local nuke
All for only a cheap total of 96 energy

Sonar's use is a bonus, especially for its potential to allow Banshee's use in certain fights like against bosses

Some recommended weapons include

Proboscis Cernos for extra gathering CC
Grimoire with perhaps a Netra Invocation or Vome Invocation
Something explosive to finish enemies off in crowds if needed
Any slam or range-focused melee weapon to quickly deliver devastating strikes while throwing out more abilities onto the field

Yes I got bored one day, I know this build probably sucks af
