Upgrade them in tiers if needed with clan housing. I'd rather have to kill black dragons or key bosses than waste my time killing snakes 🤷♂️

I would be more likely to want to do it this way, even if you got higher level monsters to kill based on clan extermination level

Rather than being a specific enemy, maybe just make it a point based value that the clan has to achieve and higher tiered enemies reward more points. This way members at all combat levels can participate.
