NUVO RADIATION RULES
Each character starts with a radiation die (d8), construct lifeforms have no radiation die as they are immune to poison and radiation. This die increases to d10 for mutants and rad sorcerers. When you approach a zone that is glowing from radiation, roll your Radiation Die.
Depending on how close you are to the source of the glow and the level of radiation, roll more or less often:
- Low, 1/day,
- Moderate 1/hour,
- High 1/minute,
- Extreme 1/round.
Each time you roll a 1-2 on your radiation die reduce the die type (d20 > d12 > d10 > d8 > d6 > d4) and take 1 level of exhaustion for each step the radiation die has decreased from its original size. If you roll 1-2 on a radiation die the size of a d4, roll a d6 on the table below.
The radiation die never goes below d4, but a roll on 1-2 still counts as if it was reduced and you automatically gain a random mutation – roll a 1d1000 and consult the Metamorphica. The maximum number of mutations a creature can have is 5, becoming an inhuman, drooling, monster once the 6th mutation is gained.
Certain arcana and magic mitigate the effects of radiation. Any magical effects that gets rid of exhaustion levels can increase your radiation die by 1 step up to its normal maximum. Other arcana can also restore your radiation die – for example, potion of vitality, and greater restoration refreshes the Radiation Die by one step, up to its maximum.
At lower levels protection from poison can be used to increase the die. This does not work automatically on radiation poisoning – the caster must make a spell check against DC 25 if they succeed they immediately refresh the Radiation Die by one step, up to its maximum. If they fail they must spend a week ministering to the creature with radiation poisoning to refresh the die. No other strenuous activities can occur during this time and the poisoned creature is bedridden as well.
ORIGINAL RADIATION RULES
ontact poison effect the severity of the exposure determines the lethality of the dose (and the DC). Creatures that are exposed to radiation must make a Constitution saving throw each round or suffer levels of exhaustion, as set out in the Radiation Damage table.RADIATION DAMAGE
Radiation is a new damage type which is a powerful form of poison damage. When a creature does radiation damage treat it as poison damage with the following additions:
- If a save triggered by the radiation attack the creature also gains 1 level of exhaustion when it takes damage from the attack.
- If a creature is hit by the attack – even if no damage is taken – the attack strips away poison resistance by one step for the rest of the encounter. This will eventually make the target vulnerable to poison damage. This occurs before applying damage. For example, a green dragon which is immune to poison damage hit by radiation would have its immunity reduced to resistance. If it is hit again by a radiation attack the green dragon would lose its resistance to poison. Another hit from radiation damage would make it vulnerable to poison damage.
- A creature that rolls a natural 1 on a saving throw triggered by a radiation attack is mutated.
- A creature reduced to 0 hit points is dead and turns to ash and all that is left is a morbid shadow burned into the floor where it died.
