here are some hints to beat annihilator: animus, you need to reduce his spirit, this is how i beated him, he will hit 0 most of the time, and if you make sure mardek resists aether it will be easier, i beated him first try with this tactic, but i first beated all solo and the champion arena, i hope this will help
this is very useful, when you use elwyn and play her ballad of balance, it also helps with potions. so if everyone got hit by an attack like tsunami you can throw a figjuice and heal everyone for 500 hp
you might to improve the game to a 10/5 add specials to the different types of animals, for example the puinguin goes faster when he is wet but then takes more dmg from a thundercloud
