I'll start by staying I'm brand new to D&D. I just made my first character and started my first campaign last week. I am playing 5e with a forest gnome ranger based on the specs in the PHB. We are in the midst of the Sunless Citadel adventure from Tales from the Yawning Portal.
My Ranger just reached level 2 and thus now gets some spellcasting abilities. However, being new to the game, I didn't know what sort of equipment to buy when I did my character creation, and so I never bought a component pouch. I'm now in the midst of a dungeon and picking my first spells.
I guess my question is a two-parter:
When am I likely to have an opportunity to buy a component pouch (or get material components); and if it's not soon, when picking my first spells, should I avoid ones with a material component, e.g. goodberry?
