An Acquired Taste

Starting at 1st level, you are immune to poison. You can cleanse poison in foods within 30 feet of you with a 10 minute ritual. 

Gills of the River King

Starting at first level, the River King blesses you to have a swim speed of 30ft, and you can breathe underwater.

 

At level 6 this increases to 45ft. At level 10 this increases to 60ft. At level 14 this increases to 90ft.

Abyssal Voyage

Starting at 6th level, you can call on the River King for safe passage. You create an abyssal passage to somewhere you've been previously. As many medium sized creatures can travel though as your warlock level. Large creatures take up two spots. No creatures with a size over large can travel though your passage.

Once you use this feature, you can’t use it again until you finish a  long rest.

Devour

Starting at 10th level, you can store items in an eldritch stomach. The combined weight of the items cannot exceed 200lbs, but there is no size limit. You can choose what items you spit out, if you wish to spit any out. The range of the spit starts at 120 feet. For every 5lbs you're spitting out, the range gets reduced by 5 feet. The damage is 1d4 blunt damage per 5lbs of material you spit. If a creature is stored inside, you can spend a turn to refresh the air inside the stomach. The air inside lasts for 5 minutes of a medium creature, 10 of a small creature, and 20 of a tiny creature.

River King's Gambit

Starting at 14th level, you can attempt to make a deal with the River King. When you make this deal, the DM rolls a d100 to decide your fate. Every 10g you sacrifice adds +1 to roll. The more gold spent, the less respect the River King has for you. On an unfavorable outcome, he will punish you. Maximum punishment is being put to 0 HP.

Once you use this feature, you can’t use it again until you finish a long rest.
