How to play:

• Obtain some energy.
• Press 1, then 2, then 3.
• Execute extermination.
• Stay in the light to obliterate.
• Stick to the dark places if need to afk to open the door to pizza delivery.
• Recommended Vazarin Focus for self-healing protective dash (and healing your teammates too).

Replace [Adaptation] to [Ice Spring] for cool jumps or whatever with Vazarin polarity if you're not running high level content.
Replace Arcanes to Arcane Precision + Arcane Velocity if you're running secondary more than primary. Or melee, if that's your thing; I was tired of spamming E two years ago. Or replace them with whatever, it's pure minmaxing and you'll probably be decent without any arcanes at all.

If you don't have Umbra Forma yet, you can remove Hall of Malevolence for the time being - that way you'll fit just into 0 capacity and lose some more convenience in damage scaling, but still will be good.

Further improvement: add aura forma to be more flexible with your goals.

On the edge: you can remove [Primed Flow] and replace it with anything you want from Naramon polarity storage, but keep in mind that you need 194 energy to cast your 3 abilities from 225 total reserve; single [Energy Siphon] behind the wall will cripple your performance that instant, combined with nullifying you'll effectively will be stripped down to your gear efficiency. If you're speedrunning low level conent, this slot could be replaced with several mobility mods of your choice, such as [Maglev], [Rush] or [Toxic Flight]. Or even with [Coaction Drift] for team composition, but this will probably require you to polarize aura slot first.

Nice things: you can ask your teammates to hug you while casting 2 for INCREASED CREW MOTIVATION.
Or hug someone yourself, spread the love (love is: 97% bonus damage for 51,5 seconds)

Weapons: anything you can crit and do headshots with. [Ignis] for primary is very hot.
