Eldritch Blast/sandbox

Pact Choices
Each Warlock must select a Pact at level 1. This is a separate toggle feat. When toggled on, the Warlock's Eldritch Blast deals an additional 1d4 damage for each even Warlock level, for a total of 10d4 at level 20. Each pact deals a different damage type and can be mitigated by a saving throw (unlike the base attack). The DC is as a 9th level evocation spell.

Shapes
The default Eldritch Blast goes in a straight line. It doesn't home in, and enemies that move may avoid it. Eldritch Blast Shapes, available as toggled enhancements, alter this effect. Different shapes scale differently with Spell Power, as shown.
