Phazon DamageSeveral abilities and effects refer to Phazon damage. Phazon damage is a special type of acute radiation, and thus ignores damage reduction, resistances, and hardness. It affects both creatures and objects equally well. Phazon damage is considered to be the result of direct contact with a severe Phazon radiation source. Certain effects provide resistance to Phazon damage specifically, which does not normally protect against other sources of acute radiation.
Phazon EnergyPhazon energy is a special kind of energy used by some classes and modules in the Metroid adaptation. Phazon energy functions as normal energy for the most part. However, at the beginning of each of your turns, you suffer Phazon damage equal to twice the amount of unexpended Phazon energy you have allocated to energy receptacles. In exchange, certain energy receptacles (primarily those with the Phazon descriptor) grant additional benefits when Phazon energy is allocated to them. Phazon energy can sometimes be temporary energy, too. If so, use the rules for temporary energy over the rules for Phazon energy to adjudicate any contradictions between the two types of energy.
Phazon ToleranceSome creatures are able to tolerate limited amounts of Phazon exposure. This is referred to as Phazon tolerance. A creature with Phazon tolerance ignores the first one or more points of allocated Phazon energy, the exact number being given in the ability that grants tolerance, when determining the amount of Phazon damage taken each round, if any. This can reduce the effective amount of allocated Phazon energy to 0, but not below. The Phazon energy still functions normally otherwise, providing all of the normal benefits of being allocated, including special benefits for allocating Phazon energy specifically. Phazon tolerance from multiple sources stack.
As an additional benefit, any creature with at least 1 point of Phazon tolerance is immune to mild Phazon radiation. This does not provide protection from other sources of radiation, nor from Phazon radiation equivalent to light or stronger, including direct contact with mild Phazon radiation sources and Phazon damage.
The Phazon SubtypeCertain creatures are infused with Phazon. Rather than killing them, the Phazon becomes an integral part of their biology. Such creatures have adapted a symbiotic relationship with Phazon. Some even produce the material internally through biological processes.
TraitsPhazon creatures have the following traits:
- Immune to Phazon radiation of heavy or less. This does not provide protection from other sources of radiation, nor from Phazon radiation equivalent to severe or stronger, including direct contact with heavy Phazon radiation sources and Phazon damage.
- Phazon creatures have Phazon tolerance, allowing them to allocate Phazon energy without damaging themselves. The amount of Phazon tolerance a creature has depends on its Hit Dice, as indicated on the table below.
- Immune to the sickened condition.
