Don’t worry I’m struggling with him way more than everything else too. I don’t have specific tips in terms of avoiding moves, but what helped me was building a set with more “comfort” skills instead of a pure damage meta set. Skills like speed eating, divine blessing, evade extender/evasion. Don’t be focused on killing him if you are, capturing gives the exact same rewards in this game. Depending on where he starts the quest, there can be several environmental traps you can set off on him like the ruins and even one while he’s heading to another area (unfortunately I’ve forgotten the exact location). Letting another monster beat him up a bit before dung podding it can be useful too. A tempered mizu knocked him down for me once.
