enmity's embrace and mercenary resistances

I'm playing aurabot with merc, but i have problem with one of my mercs. If i put up Enmity's Embrace on my Manyshot mercenary - she always got 0 fire resistance. I've tryed almost everything, i've tryed white sockets with The Untouched Soul, i've tryed to buy 120+ fire res rings, i've tryed link myself with mercenary and use bismut and ruby flasks with Ceinture of Benevolence, i've got purity of fire and purity of elements. Every time when i put up this ring on Manyshot merc - she got 0. If im trying to put this ring on my other type of meer it works properly.

Same problem with Thunderquiver merc

Enmity's Embrace gives 65%+ reduced fire resistance, Cowl of the Cryophile gives 50%+ reduced fire resistance.

With 100%+ reduced fire resistance, your fire resistance will always be 0.
Just like how sufficient reduced reflected damage taken makes you take no reflected damage.

I've tryed with Cowl and with out it. Can you explain why on other merc ring works perfectly?

You posted 4 screenshots for the Warpriest Merc: gear + stats without Enmity's Embrace, gear + stats with Enmity's Embrace.
Without Enmity, the merc had 292% uncapped fire res.
With Enmity, the merc had 99% uncapped fire res.
99% / 292% ~= 33.9%, so I assume your Enmity's reduced fire resistance roll is 66%.
292% * (1 - 0.66) = 99.28%

You posted 4 screenshots for the Manyshot merc: Cowl + stats without Enmity's Embrace, Cowl + stats with Enmity's Embrace.
With Cowl and no Enmity, they had 266% uncapped fire res. Without Cowl or Enmity, they should have over 500% uncapped fire res.
Cowl + Enmity = 0% Fire Resistance, because 500% * (1 - 0.66 - 0.50) = 0%.

While you have more than 100% reduced fire res with Cowl of the Cryophile and Enmity's Embrace, % reduced modifiers cannot lower values below 0% so that you can't use reduced modifiers to turn very negative values into positive ones, and vice versa.

wooops. You are right. My bad
