What level should somone be before they attempt the Kalphite Queen using Veracs method? (With team)

It's recommended to have 90-95+ ;)

At least 75 in Combat Stats, especially HP and Attack. There have been several players with lower stats tacking on the Queen as team, but this is dangerous as the Queen can hit up to 31.

Ok thank you both

It does also depend on how many are in your team though. If, for example, there are just two of you, you should definitely be 100+ (without summoning).
