At low levels this is great xp and if you start grinding it early you could take the rc outfit to do bloods and get more runes . I agree it's a heavy grind but like what is stated already the mini game may get a buff after the reviews it gets. I wouldn't completely recommend do this if you already have bloods unlocked as of now though. My rc was 27 when I started and was averaging 22k xp and vs this to lavas there is no input (gp) needed to do this just time spent. All runes are 100% profit which I know isn't much in some cases and tbh idk how much it is to do lavas as I've never done them but I do know you have to buy rings of dueling to vs this to the mini game which is a GP loss compared to a minor profit from the mini game plus the potential pet. I can't completely bash the mini game but it could use a buff to pearl drops from chest.
