The Eldritch Invocation "Book of Ancient Secrets", according to the Player's Handbook, allows the Warlock to add two first-level rituals from any spellcasting class to the Tome of Shadows.
It also allows the scribing of additional rituals, if found on a scroll or in a spellbook - with a restriction of the spell having to be of a level equal to or half the Warlock's level (rounded up).
In effect, it is similar to having Ritual Caster for every spellcasting class.
Orcpub2 does allow the selection of the initial two ritual spells, but not the selection of additional rituals after that. I would like to see this inaccuracy corrected, as it prevents me from using Orcpub to track my character's full progress.
