So I pre-purchased the digital deluxe version of GW2, and was wondering if someone could tell me how to use these items or when to use them. I know this is a total noob question, but I just used my golem banker, and he disappeared after a couple minutes and is not in my inventory anymore. So I am kind of curious as to how to/when to use the rest of the items.

Summon Mistfire Wolf Elite Skill
Miniature Rytlock
Golem Banker
Chalice of Glory
Tome of Influence
