Oozes are unique and fun creatures to encounter, usually adding a challenging problem for adventurers. There are many different oozes and even a complete subset of them that specialize in eating wizards and artificers.
Unfortunately, many players rarely get to witness the versatile and powerful skillset that oozes, jellies, puddings, and oblexes have to offer, much less wield it.
The Plasmoid gives a collection of abilities that demonstrate the power of such beings, but it is a playable race and thus does not offer as much as a subclass.
Slimy Mad Scientists on the other hand, have changed themselves to be more like various members of the Ooze creature types. You will get more variety in this subclass than any subclass that I have put out so far, or any subclass in official dnd 5e for that matter.
Like the Armorer, there are multiple possible aspects of these powers that you can choose to manifest. This gives you insights into a bit of lore, and the abilities of various types of these beings. Not to mention, this also provides a ton of choice empowerment.
With this build, you can choose a different form at dawn.
Each subclass has a fun and unique set of powers and abilities. Small spaces, not a problem. Poisoned by a spy, no problem either. You are resilient, and can bring down the most heavily armored of foes. You are a slimy soldier, and you will make an impact.
Rise above your fallen enemies and add absorb their vitality.
