Spirocs in TD are somewhat off the beaten path, although it has gained some popularity. Spiroc provens backstab for around 300. When hasted a spiroc proven can kill about 1 feared spiroc every 30-45 seconds. No need for snare for fear kiting since the island is so open, but a duo partner would help with the pet stealing xp.
I would not try the Hole entrance at 45 solo. If a named spawn's it's pretty unlikely you'd be able to solo it. Think nameds are level 49? or close at least.
