I'm going to be playing in an adventure soon (Hoard of the Dragon Queen, I think?). I have been thinking about playing a bard (lore) with a two level dip into warlock. The goal with taking levels in warlock is to get some decent ranged combat ability (Eldritch Blast cantrip with Agonizing Blast invocation, etc.) for a character who will otherwise stand back and look to throw out some buffs/debuffs and healing if necessary. The character will also take on some of the the tasks of being a rogue (will take background as a criminal to gain access to skills and tools). My question is, has anyone had any experience playing a character with this kind of build? How did it work for you? At what point should I take the two levels of warlock? I am not entirely certain of party composition at this point, but I think there will be a cleric and at least one tough fighter type (possibly a barbarian). I suspect my decision of when to take warlock levels might depend on what I'll be needed to do (e.g. if I am needed to provide backup healing, I may need to take bard 2 before going into warlock). Any advice/suggestions on this build would be appreciated.
