Hello tabletop peeps! I have completed a monster design for my first ever boss creature, and I wanted to get some quick feedback. This is all based on a previous post where I got ideas from y'all, here: https://tildes.net/~games.tabletop/1cjn/designing_my_first_dnd_boss_fight_with_a_giant_mimic_5x_lvl_5_characters
Players are a group of 5 lvl 5 characters, fairly magic heavy and lower hp overall.
The boss creature is a mimic that appears to be a large stone fountain with blood in it. If a PC touches it or stabs it, then they (or their weapon) will be grappled for the start of combat. At that point, the mimic will sprout 6 tentacles that each can travel up to 40ft from the main body and wield a weapon. All tentacles will operate on the same turn as the main body.
Healing Pool in the boss room
The boss room is a large room with a pool in it where blood is mixed with water that has flowed over a magic crystal to produce a healing solution. The idea is that the PCs will figure out that they can either heal themselves by dipping into the pool, prevent the boss from getting close to the pool, or that they can break the magic crystal to prevent the boss from healing. Several of the boss abilities reference this pool.

Potential Adds
There are two skeletons in the room that can be resurrected by the Handy Tentacle with it's "throw juice" ability, should the fight is too easy for the PCs or they are hanging back too far. These adds are Boneknights from page 6 on this link: https://www.gmbinder.com/share/-Mv5UKsPhrHkBqSf9vo1
Conclusion and Questions
Is this a fun boss? I aim to have the tentacles each fighting a different person, so I don't think I'll wipe the party out too quickly, but I know of the mystical "action economy" and I might be overdoing things.
Also, how do I rate the CR of such a creature? And how much gold should a party earn for such a fight? Thanks for helping out a new DM!
