Quick Reference
Running This Encounter
Killer whales are apex predators that hunt in coordinated groups, using their intelligence to execute complex strategies. The DM should emphasize their speed and mobility in aquatic environments, using the full three-dimensional space of water combat. They can communicate with each other to flank and isolate targets, making them formidable opponents even for experienced adventurers. Consider using multiple whales to create a challenging encounter that rewards tactical positioning and teamwork.
Combat Tactics
Killer whales prioritize isolating weaker party members from the group, using their 50 ft. swim speed to circle and attack from unexpected angles. They use their bite attack aggressively but retreat to deeper water if heavily damaged, potentially leading to a chase sequence. Multiple whales coordinate to flank targets, granting advantage on attacks while forcing the party to spread their defensive resources.
Environment & Setting
Open ocean, deep bays, or large underground lakes provide ideal hunting grounds where killer whales can use their speed and mobility to full effect. Kelp forests, ice floes, or shallow reef systems add environmental complexity and hazards that complicate both pursuit and escape.
