Hi everyone I'm fairly new to the game and I just had two questions about the job I picked (Monk).

Firstly I see that MNK uses two abilities from the lancer tree I think its Blood for Blood and invigorate, do I need to get to the corresponding lancer levels in order to unlock these for monk?

Also, since I am level 49 now about to push into the newer content, am I going to be expected to already have those abilities for the leveling dungeons or can I just put off leveling the lancer until I start doing more end game stuff?
