Tip: Counter to Darkness?

[JimMorrison]

Vulnerabilities and resistances are cumulative.

So if a unit is 100% Fire vulnerable, it is in fact -100% Fire resistant, meaning that if you add 100% FR from items, then he is at normal damage.

Yes, buring perls+dragon helm+fire plate = 150% FR and only requires const 2 and 15 fire gems (less with hammer). Adding a fire band or a charcoal shield (const 4, 5F5E each) provides the remaining 50% FR. See, it is not that hard to make a Mandaha fire immune.

Now Lanka does not have F or E mages, and needs bless for their sacred troops. So forging such gear is quite difficult for Lanka.
