DEEP SEA SUMMONS of CRABULOUS SAHUAGINS - 1.0.0.19,  functional version 2.0
The Sea Chest with the summon and spell items is in the Tutorial Chest on the Nautiloid (or in your Summoned Tutorial Chest) and in your Camp Chest. Most are sequentially distributed in the treasure tables and will appear in game in certain thematic locations. 

:: REQUIREMENTS ::
• Patch 7, made in the official BG3 Toolkit

:: FEATURES ::
• Immersive distribution and thematic permabuffs and elixir-type replacers
2 unique eternal Create/Destroy Water-type cantrips in a jar
• 20 Turn cantrip Greater Invisibility (with concentration) in a jar
• Unique Water Whip cantrip in a jar
• Themed Aquatic Misty Step cantrip in a jar
• 3 unique tiered-strength Crab reusable summon items
• 3 unique tiered-strength Sahuagin reusable summon items
• 5 Unique Kuo-Toa Summon spells on resuable summon items
• 4 unique musical instruments, playable by all races, thematic
• 2 Flumph summon spells
• magic armor and themed weapons
• Oceanic Origin in a jar, make your character have sea powers with one swallow
• separate scrolls for all spells
• containers for Kuo-Toa summons and Water spells, learn by drinking potions or unlock from weapons/armor

:: Item-based Spells::
Use the spells by dragging the item into your hotbar or use from inventory just like a spell scroll. Get rid of the spells by removing the item from the hotbar, then put the item from inventory back into the Summoned Tutorial chest and despawn it.

::RECOMMENDED MODS ::
These are not necessary, but if you want the ability to uninstall then a Summoning Tutorial Chest mod is helpful. I use the Item Shipment Framework.

:: KNOWN ISSUES ::
• Sahuagins have no sneak animations
• Because the crabs and sahuagins do not have casting animations for some things there is a stutter while nothing happens when casting Aquatic Camouflage or High Tide/Surf's Up, but I did have the spells make wet sounds
• Kuo-toa music animations cut in their faces. cant help that. still looks cool. They play the flute with their gills - pretty cool.
