I've just returned to this thread as I'm levelling a red-side widow on Torch, hit the level 24 respec and am using Gulbasor's Build 4 Fortunata guide. https://forums.homecomingservers.com/topic/11319-best-of-both-blood-widower-fortunado-build/
My white side Level 50 Widow, Funnellweb, is a beast, but I wouldn't recommend her unless you have a stupid amount of inf to throw at the build.
She is a favourite character of mine, and thus NO expense was spared in making her feel appreciated, but my bank balance felt it.
All six Superior Dominion of Arachnos, and all six Superior Spiders Bite, plus all six of Superior Blistering Cold, Ragnarok, Armageddon, Hecatomb, and Apocalypse. All done in the days where you didn't see change from 20 million an enhancement, so a long way to a billion inf just there, at least back then.
Then there's the six Shield Wall, six Reactive Defenses, five Panacea etc.... Even all the IOs are at 50+5
1293HP, capped psionic resist (a Widow speciality), resistances running around 35% except energy and negative at 12.5%, 44% damage bonus and 177% recharge bonus so she never ever slows down.
Works well with my play style, but oh so expensive.
