What should I get with 22,610 gems?

I want temple guard now, apparently it has a new ability:

Sword of the Temple Guard Update

Sword of the Temple Guard just got an item ability, and it makes you a giant! Harness the power of the ancient paladins and grow larger and blast your enemies back for 5 seconds! The sword only has a cooldown of 10 seconds, and even the heaviest of foes will be blasted back! Enjoy [Screen Shot 2020-10-26 at 9.48.28 AM]

but the sword is 4800 gems, so I can get Illia and temple guard with 1,810 gems left, or I can get Illia and Arryn with 2010 left and save up for temple guard after. What should I do?
