How to Beat the Pharaoh in +1 Anime Eyes
Train your Chakra, use a Chakra-boosting pet and return to the Pharaoh when you're stronger.
If the Pharaoh is taking too little damage, leave the fight and click to build more Chakra before trying again. If you have a pet that boosts Chakra, equip it while you train.
One player who struggled to damage the Pharaoh equipped an epic pet that multiplied Chakra power, trained to around level 200, then returned and kept attacking. They reported passing the Pharaoh on that attempt. The pet and level are an example of a successful run, not established requirements.
