When used with Harrow it's very easy to stun enemies to hit the headshots required for [Zymos]'s effect. as well as boosting crit for those juicy red crits.
the bees deal huge amounts of slash procs due to hemorrhage with the innate guaranteed impact procs, and crit multiplier buffs resulting in well over 100k damage slash procs in an AOE.

Both Crit damage and Crit Chance are squared on the bees meaning there is a 79.2x increase in damage and 207.36% crit chance.
with the formula
Crit level (modded crit multiplier - 1) + 1
where 201% - 300% is a T3 Crit level
this gives a total of 3 (79.2 - 1) + 1 which is 235.6 TIMES base damage

or a total of 1,749,047.28 / bee
[Zymos] creates a total of 6 bees (not scaling with multishot) giving an overall per shot damage of 10,494,283.68

Or you could use Harrow its a 4x multiplier to the crit chance on headshots. essentially maxing
Crit level to its max (Level 5) which further increases damage up to 392 TIMES base damage.

Or total of 2,910,129.6/ bee
or overall damage to 17,460,777.6

Viral also effect the damage of the slash procs adding even more damage from 100% at one stack to 325% (+25%per stack) at max stacks

34106421.96 Without [Harrow]
56,747,527.2 with [Harrow]

Any flat crit chance mods are applied, They are multiplied by modded critical chance once, and add again last. (EG: Citrine)
Critical Chance = ((5% × (1 + Modded Crit Chance)) + Flat Crit Chance) × (1 + Modded Crit Chance) + Flat Crit Chance
Critical Damage = 2.3 × (1 + Modded Crit Damage)2
Subsuming Zephyrs Airburst Rounds increases damage by a max of 500% (5X)

Nidus and Xaku can use parasitic link and gaze respectfully to produce an invulnerable fountain of bees

---- I am unsure if projectile speed effects the bees, however it does make zymos easier to hit heads with at a distance in my opinion so is a flex slot for any other mods you may want ---
STAY AWAY FROM PUNCHROUGH as it prevents bees from being created when hitting headshots.
