Poisonous Poisons

REQUIRES (almost) ALL DLC

REQUIRES JIP LN

This mod started as a personal pet peeve of mine, seeing as tribal and makeshift remedies like Antivenom was pretty much everything that the world of New Vegas knows about poison treatment, and somehow they have an amazingly wide spectrum of effectiveness. Looking around the Nexus for inspiration, I first came across MadCat's Antidotes mod, which offers a pair of new ingestibles to immunize your character for a short time prior to a fight against Cazadores or Scorpions. Not much, but an excellent start. I also noticed that going by the game file's names, the different bottle models used for the weapon poisons in New Vegas were initially intended for such a system, having different antidotes against different enemies, before they decided to dump them all together into antivenom.

I also wanted for being poisoned to actually matter somewhat, even if curing poisons was ultimately easy, for it to actually be able to affect your character in nasty ways, and take an awful lot of time and pain to clear out so that waiting it out would be simply impractical. Like in the classic Fallout games, where getting poisoned by a radscorpion sting ultimately didn't do much, but the effect could last even several days if you didn't take antidote.

Finally, as for the bottled poisons you can use in melee, I also wanted them to have more interesting effects and be included by the above ideas as well, something for which I drew inspiration from Alceister's Poison Overhaul mod, adding a new perk to make poisons and the Medicine skill more useful.

In this mod I've touched a lot of stuff, and while I believe the end result can still be improved (of course), hopefully you'll find that poisons are now something more of a menace... well, at least if you let them touch you and don't go swimming in Antivenom; and that if you favor the Medicine skill you might have more fun with them as well.

Poison Buff and Overhaul

All poisons should now be simply terrible for you and your enemies. Bottled poisons had their effects buffed up, and in some cases new effects were added. Mother Darkness will drain the target's movement speed, Bleak Venom will damage or cripple the chest, Dark Datura drains Agility and Action Points whether you or White Legs use it. Tremble will cause the target to trip and fall due to violent shakes every few seconds, even dropping any non-Unarmed weapon he has drawn, making it more useful against both creatures and NPCs. All poison recipes are categorized under a new subcategory in the Campfire menu.

Animal poisons are even worse. Green Gecko and Tunneler poisons were restored which will drain your Strength and cripple your legs respectively. Green Gecko poison
