Build

Whip'em

This build centers around making the whip into a high speed horde clearing monster with great survive-ability with soul siphon and eat-a-punch. I only use the Boomerang for flying targets too high up to reach and to increase dps on bosses, as the whip does struggle with them somewhat in my experience. Spells don't matter too much, so just use what you like. I went with Fireball for breaking gold as I like to full clear everything the lighthouses reveal and Bridge to improve mobility, and I flex the third slot to whatever I feel like, though I do prefer "set and forget" spells like Wisp or Rain. The build planner doesn't appear to support the "charge speed" upgrade for the whip, but do spend all the points you can into it, as it makes a big difference when fighting heavy enemies.
