This ability is activated passively when Blue Ooze comes into contact with a weapon that can be corroded (this covers to understanding points automatically at level 7 you cannot gain understanding points in combat any other way). When you consume an object you learn about a category of your choice (Ex. Immunities, ability scores, languages etc.) Roll a D4 to determine how many things you learn about the category. Alternatively you can earn understanding points through learning the Shape of the object. Understanding points are points which are used by Amorphous to transform into objects and other creatures. There is conversion rate for making Simple Understanding Points into Intermediate then Complex and so on. You CANNOT consume magical items however but you deal acid damage which is identical to Acid Splash except it is automatic damage to any living creature you eat. Once you reach the max understanding points you can convert them all into 1 permanent point for that tier so you have an additional +1 when transforming into an object of that tier

Understanding Points Gain based on complexity            ([point gain],[max points],[point conversion/minimum roll required for transforming into an object of that complexity])

Simple - 1, 21, 3 (Ex. Cup)

Intermediate - 1, 45, 5 (Ex. Sword)

Complex - 2, 80, 10 (Ex. Simple machine)

Scholar - 3, 100, 10 (Ex. Person)

Simple Way

tell your DM what you want to turn into and roll for deception 

Complex Way

Amorphous allows you to change your form instantly and can be used halve damage taken by compressing yourself since you can change to be less than an inch in any direction. Changing your form beyond simple shapes requires Understanding Points which requires you to roll for Deception you can use Understanding Points when changing into an object. Transforming requires you to roll a D20 (your DM determines what number is required for a successful roll) you have to choose whether not to add Understanding Points to improve your roll BEFORE rolling. The Understanding Points are not added directly but instead you must use the amount of points you can convert to determine how big of a bonus you can get for one turn (i.e. you have 15 Simple Understanding Points the conversion rate is 3 meaning you can add a max of plus 5 for your bonus). However if somebody does an investigation check and rolls higher then your deception you will be found out. If you are transformed AND hardened you roll with advantage because the harden makes it harder to tell you are not authentic. You can harden part of your body in order to do this you must roll [roll]1d20[/roll] the result divided by 2 rounded down is your hardness on the Moh's hardness scale. It takes another action to return to your original form. when your body is hardened it is completely fixed in that shape until you stop concentrating. Only through

you as far as your abilities you are very similar to grey ooze but you were also gifted with elemental powers since you were summoned from Jubilex himself 

If your bond is strong enough with someone you can relay images, emotions, or the intended action which is usually perceived by them in a similar way to suggestion you can also feel their presence passively no matter how far they are you can sense (as long as they are in the same dimension)

any enemy that uses Identity or similar ability on you to gain insight to your mind through magical means is dealt psychic damage
