(3.P) Warlock, Archetypes, Baptisms, and Tactical feats (PEACH)

[Deviston]

I can see adding the element choice as a Dark Secret. Grabbing two more elements as a Advanced Dark Secret, able to be taken twice, picking different elements each time.

Also making the Wisdom to touch attacks a Dark Secret.

Zen Blasting: Select either melee or ranged touch attacks. You may substitute Wisdom for your normal attribute when making this form of touch attack in regards to your eldritch blast invocation. you may select this dark secret twice, its effects do not stack. The second time you must choose the touch attack form you did not choose when selecting this dark secret the first time.

Now, what do you think about the class?

Edit: Also, unless there is a homebrew, the warlock doesn't get a fireball-like invocation.
