First hand tips translated from Chinese EO site! It seems like not easy to apotheosize but I believe it's worth the challenge. Stay focus and get prepared! ;)

Most apotheosis challengers fail to apotheosize because they didn't manage to pass the level of challenging Athena Servant or the final level of thunder attack.

First, before starting the challenge, you'd better invite several teammates to go with you. So you can spend less time since more players participate in the challenge. A warrior who wants to apotheosize can ask a mage to go with him, so that when your converged eudemon is about to die, you can ask the mage to make you invisible. This is very important. Otherwise, you will certainly fail in the challenge!

Put enough HP potions on you when come to the level of thunder attack. Of course, you have to buy the potions in the EP store. Those bought in the outside store are useless. Don't tell me you have no EPs. Put the HP potions in the numeric keys. Press the numeric key directly when you are out of HP. Keep drinking the potions when you get across four corridors. You can pass the level easily following the instructions. (To save our time, I'll skip this part~). In the final level thunder attack, you'll have to endure 9 rounds of attack. You just need to keep drinking the potions you prepared for each hit. Keep drinking, otherwise you cannot get across this level. In this way, you can be apotheosized and become a god easily. If you want to apotheosize, hurry up to buy a 40-star eudemon ;)

Have fun in apotheosis!
