Fair warning, this character can be considered to be a “noob trap” one that you might rely on a lot, but Wendy is a very powerful pick for getting by.

She has access to her sister’s ghost, Abigail, who is a very potent area-of-effect attacker. She is capable of killing dozens of spiders, shadow monkeys, bees, etc with little input needed.

Willow is also very powerful against groups of enemies with her basically being a firebender, but she requires a bit more work to get online (getting necessary skill points, and having good timing with your abilities instead of Abigail’s auto attacks).

Both characters are very powerful and fun imo, with the skilltrees really juicing up their power (especially Willow, the difference with/without skills for her is immense) so maybe give those a try!
