+1, very nice suggestion and indeed kinda makes you choose between it and other beneficial pets (like yosh r fairy or variants of those).
Not sure bout the 1/5k from superior rate though, I mean best case scenario that translates to 1/25k for revs, so like 10ish k kills with high risk orb as a rough approx?
This would make the pet hella rare and super expensive, meaning that it'll essentially be a gambler pet as regular players will be unlikely to obtain it and if they do it means they have like a cold 10t to spare.
I mean its a matter of personal preference obvs, either have this pet super rare and over time have it as a rich get richer kinda pet or make it more common but add like an autoskull feature or so to add a fun little risk/reward tradeoff to it?
