Mermadic Bloodlines
This mod adds three inheritable Mermaid bloodline levels with Hydration, Fitness, and Singing bonuses to The Sims 4.

Mermadic Bloodlines by baniduhaine adds a generational inheritance system for Mermaids in The Sims 4, allowing their supernatural abilities and advantages to become stronger across multiple generations. Inspired by the Spellcaster Bloodlines system from Realm of Magic, this mod gives Mermaid families additional benefits for maintaining their occult heritage.

The mod introduces three bloodline levels: Weak Mermadic Bloodline, Strong Mermadic Bloodline, and Ancient Mermadic Bloodline. Each generation can inherit a stronger bloodline from their Mermaid ancestors, receiving bonuses that improve Hydration management and skill progression.

Mermadic Bloodline Benefits

Each bloodline level provides different advantages:
  • Weak Mermadic Bloodline: Reduces natural Hydration decay and Hydration loss from active abilities by 10%. Fitness and Singing skills also develop 10% faster.
  • Strong Mermadic Bloodline: Reduces natural Hydration decay and Hydration loss from active abilities by 20%. Fitness and Singing skills develop 20% faster.
  • Ancient Mermadic Bloodline: Reduces natural Hydration decay and Hydration loss from active abilities by 50%. Fitness and Singing skills develop 30% faster.

These bonuses help later generations maintain their Hydration more efficiently while developing their physical fitness and musical abilities at an increased rate.

Generational Inheritance
The bloodline system follows inheritance rules similar to those used for Spellcasters in The Sims 4.

The progression works as follows:
  • Mermaids without an existing bloodline can pass down a Weak Mermadic Bloodline.
  • Mermaids with a Weak Bloodline can pass down a Strong Bloodline.
  • Mermaids with a Strong Bloodline can pass down an Ancient Bloodline.
  • Mermaids with an Ancient Bloodline continue the Ancient Bloodline in their descendants.

However, this progression depends on the offspring being born as a Mermaid. If a descendant inherits a bloodline but is not born as a Mermaid, the inheritance progression reverses rather than continuing to advance. The bloodline only becomes stronger across generations when the offspring are also born with Mermaid occult status.

Mermadic Bloodlines requires The Sims 4: Island Living and Lot51 Core Library. Installing the mod without Island Living can cause LastException errors because the expansion provides the Mermaid occult system.

The mod is also compatible with Enhanced Mermaids 2.0 by SpinningPlumbobs, allowing players to use both modifications together.

Mermadic Bloodlines is a great addition for players who enjoy supernatural family storytelling, Mermaid legacies, and generational gameplay. It gives Mermaid families a reason to preserve their occult heritage while rewarding descendants with increasingly powerful inherited bonuses.
