It is completely normal. At this point I had 8k tho. Pop your catalyst and stuff dies in 2-4 ticks.
Base damage is low, I guess to compensate for the fact that you cast and forget. Use the shockwave trap in addition to the incineration one, use the catalyst whenever it is ready and try to use it effectively on crowded areas. Kiting enemies is actually a good idea.
Early game equipment is in this thread, aim for Vizjun set as soon as possible. Use Pefrect diamonds in weapon and Zod crafted jewels for the rest.
