KCGemini | Grounded: Infused Mant solo [NG+4 Whoa! difficulty - No damage] @KCGemini | Uploaded May 2024 | Updated October 2024, 15 hours ago.
Official Release v1.4.0.4495

This video exists to show why I never put up a non-infused Mant video (or Assistant Manager, for that matter). If anything, consider it a showcase of the Fresh Coldtana/Breathslayer.

His Infusions:
Increased Movement Speed
Increased Attack
Increased Max Health
Explosive Attack
Spicy Magic Attack
Shockwave
Venom Coating

As for strategies, other than using Mant's legs to kite any summoned ants to prevent them from biting you, you want to watch out for his gurgle-roar, as being right beside him during that moment will trigger his infusions and likely cause a one-shot.

Items and Equipment:
Fresh Coldtana Lv. 15 - With Samurai and a good Science Cone/Glowbasa Necklace, he gets out-DPS'd before he can do much of anything. The Science Cone here has Samurai, which is used to build up 5 stacks of +10% attack speed.

Science Cone - Friendly Fire Defense Up / Samurai / Finale Goo

*Friendly Fire Defense Up - Not needed in this fight, but it reduces damage from other players and yourself by 75%.

*Samurai - For every hit inflicted by a katana-type weapon, +10% attack speed is added, up to a cap of 5 hits (50% attack speed). Samurai's effect still works even if you switch trinkets mid-fight.

*Finale Goo - Applies the same effect as Giddy Goop, giving the enemy a -20% movement and attack speed debuff for 10 seconds.

Glowbasa Necklace - Fresh Damage Up Best / +Critical Hit Chance / Implant Weakness: Fresh

*Fresh Damage Up Best - Increases fresh damage by 50%

*+Critial Hit Chance - Raises crit chance by 5%

*Implant Weakness: Fresh - Adds a debuff that gives an enemy 50% increased damage to fresh. (On another note, this trinket effect can be mislabeled and shares itself with Implant Weakness: Sour and Implant Weakness: Salt. To test if it's actually the element in question, hit an enemy once to trigger the debuff and then hit them again to see what type of damage increased. This one is actually fresh, thankfully.)

Eyepatch Lv. 0 - Adds 10% more to one's attack but at the cost of taking 25% extra damage.

Fire Ant Arm Guards Lv. 9 (Sleek) - This armor piece has a 10% chance to inflict corrosion upon striking the enemy, which reduces defense by 15% for 10 seconds.

Greaves of the Mother Demon Lv. 9 (Sleek): Each hit inflicted has a 25% chance to apply poison or venom to the target. The poison does 16 damage every 5 seconds, while venom does 18 damage every 5 seconds.

-

Food and Drinks: (due to the cooldown for using buffs, I skipped recording those actions)
Perfect Toast - +5% crit chance and +40% to critical hit damage
Boss Sauce - +5% crit chance
Liquid Rage - +10% attack
Green Machine - 20% faster stamina recovery
Boost Juice - +20 stamina

-

Mutations:
Blademaster Lv. 3 - Although this will lower Mant's attack damage by 30%, its primary use is reducing the exhaustion timer by 90%, which is more than necessary since Samurai drills through stamina like nothing.
Ant-nihilator Lv. 3 - Increases damage to all ant types by 25% and defense by 10%. This *does* include Mant.
Cardio Fan Lv. 3 - Decreases the exhaustion timer by 30% and grants 30% faster stamina recovery.
Coup De Grass Lv. 2 - 5% crit chance, stack all the crit.
Trapper Peep.R Lv. 3 - 60% more damage from critical hits, pairing nicely with the other buffs.

Lastly, the Fire Ant Queen mount was used to deal an extra 20% damage to fire worker and fire warrior ants. I'm not sure if this mount works on Mant.
