I bring another update after playing it this class in the 1st session of a campaign, finally!

v0.1.7 Playtested Once!
  • Eldritch Blast no longer allows you to add your Charisma bonus to damage by default. This is to bring the average damage more in-line with that of a Rogue despite having more Eldritch Dice than a similar-leveled Rogue.
  • Improved Eldritch Blast now only allows you to choose 2 targets. Improved Eldritch Blast (II) now allows you to choose 3 targets instead of increasing the damage when you target multiple enemies.
  • Added the Agonizing Blast invocation to let you add your Charisma bonus to damage once per turn.
  • Fixed some invocations which grant spells. This includes One With Shadows, Spiderwalk and Veil the Eyes. This was mainly wording - the only actual balance change is that One With Shadows previously would have allowed you to cast Invisibility on other characters, but it now only allows you to cast it on yourself.
