I'm thinking about making the kraken like a boss with steps. I'm thinking that you have to get on a boat and maybe shoot the kraken with cannon at first. The cannon shots will create a wound that you can physically enter. Once in the kraken there'll be like 5 branches you need to complete in order to unlock the final room where you can finally kill the kraken from within.
Thanks for the reply! Dark Souls is a very difficult game made by FromSoftware on consoles. I'll take into consideration your suggestions! Do you have suggestions for any abilities those bosses can have?
What do you mean by seamlessly? And also have you tried linking a t-flipflop to teleport you to a particular armorstand (going back and forth between two command blocks that each have their armorstand). I might be not understandng your problem very well too :D.
