📋 About This Mod
Ever felt like radiation wasn't hazardous enough to worry about? Well think again!
This mod seeks to make radiation play an integral part in how we approach the game. Radiation damage outside of a few situations is largely inconsequential in most respects, but not anymore, especially on the higher settings.
Upon loading into the game you will be granted a holotape that will allow you to adjust the settings for the mod. You may also craft the holotape should you lose yours by looking under the utility section of the chemistry workbench.
There are two options on the holotape:
-
[]Environmental - being submerged in water, irradiated barrels, exploding cars, etc.
[
]Consumable - irradiated food, water sources, and chem effects (Nuka-Cola), etc.The Environmental settings will allow a variance between 1x all the way up to 10x in increments of 1, while the Consumable setting will increase consumed rads from 5 to 50 in increments of 5.
By default the mod is set to 2x for Environmental, while Consumable is set to 10 rads. Both settings can be completely disabled independently.
Perks like Lead Belly and Aquaperson will have significantly greater value, and even Rad Resistant, particularly when combined with Cyan's Perk Mod 2.
NOTICE: This does not affect radiation damage from weapons like the Gamma Gun or Radium Rifle.
CONFLICTS: This mod changes four records, so should be largely compatible with other mods. The record in question is the one responsible for supplying clean drinking water which sadly has the DamageRadiationWater magic effect but a value of zero, so still technically qualified as being a spell which is harmful for purposes of the script so I simply removed it to compensate for the shortcomings of the script event used to detect incoming spell effects.
UPDATING: if updating to v1. 03, you might have to go into the settings and adjust the Consumable Multiplier setting as it may not have reset since the last version.
