Build a custom Eldritch Invocation — it joins the SRD invocations in the Warlock's picker, and its benefits apply on the sheet automatically
Identity
Leave blank for none.
What the invocation does, in your own words (original or SRD only).
Mechanical Benefits
Add the effects this invocation grants. These auto-apply on the sheet and in play — e.g. an at-will cantrip, a skill proficiency, a bonus language. Leave empty for a purely descriptive invocation.
