Area and coordinates: Sastasha (Hard)
Steps:
1. Enter Sastasha HM and reach Kraken.
2. Get stunned and grabbed by one of Kraken's Tentacles.
3. Instead of being thrown across the arena like normal, dropped into the pool the tentacle emerges from, and cannot escape until stunned by another tentacle. (Tentacle may have been killed whilst grabbed? I'm unsure.)
