I am a longtime BG2 player and know nothing of ruleset 5e.
The spell Witch Bolt says "Inflicts Witch Bolt (2)" in the description. What is the (2)? Duration??
Why don't many spells show duration in their description?
Also some spells say requires concentration. What is this??
Does this mean the spell caster must stay still and do nothing else for the spell to continue?
