Infernal Corruption

The longer a mortal soul remains in Hell, the more it is naturally corrupted by the energies of the lower planes..

As a character becomes more corrupted, they may become more devil-like. While these changes may open some doors, it will close others.

A player can gain up to 7 levels of corruptions:

• A player with 0 Levels is uncorrupted
• A player with 7 levels is fully corrupted. They become an NPC under the DM’s control.
• Stages
  • Corruption Levels 1 and 2 are Stage 1
  • Corruption Levels 3 and 4 are Stage 2
  • Corruption Levels 5 and 6 are Stage 3

Levels of Corruption may come from exterior forces or from the player themselves. When a character gains a level of corruption, roll on the corruption table.

Players can choose to take on a level of infernal corruption in the following ways:

• Can take a level of corruption to reroll a failed roll
• Can take a level of corruption to awaken at 1 hit point if downed
• Can choose to take a level over a long rest
• Can absorb a devil’s essence for specific abilities
  • 1 Level if <CR10
  • 2 Levels if >CR10

Players may also receive levels of infernal corruption from exterior sources:

• If the player does an overtly evil and corrupting act, the player must make DC 15 save of the DM’s choice.
• If the player is revived from death they must make the save.
• If the player takes damage greater than half their hit points they must make the save. This save is made at disadvantage of the damage drops the player to zero hit points.

But players are also able to remove levels of corruption:

• Players can forgo other activities during downtime to attempt to remove levels
• Players can make a DC DC 20 check every level up to remove a level of corruption.
• Greater Restoration or greater magic can remove a level of corruption.
