Your two Endbringer powers have combined, synergizing and enhancing each other’s powers to new heights:
Firstly, Typhon can now let you use any of your Endbringer powers outside of your EB form - albeit with them reduced to just high T1/low T2 in strength - and its power-boosting aspect is increased from 25% to 50%;
Secondly, End-Becomer can now access your non-EB powers, and additionally allows you to temporarily replace any of your EB powers with some of your non-EB ones, boosting those powers to the level of an Endbringer while in effect;
Lastly, the Endbringer physiology granted by both powers has now compounded and evolved, granting you two cores, a half-again increase in strength, durability and density, and the ability to move your cores around your body for both your normal and Endbringer forms.
(Note: If you have Negentropy, Typhon's power boost is increased to 100%, and End-Becomer gains two 'blank slots' to boost non-EB powers with.)
