I have only ever played Pathfinder and the way it works in that system is you would get extra spell slots based on how much intelligence you had. So in this table, it shows how many more spells per day you get based upon how much more intelligence you have.
Do you get any extra spells as a spellcaster in D&D 5th edition?
This is all I could find in the D&D 5th Edition players handbook:
You prepare the list of wizard spells that are available for you to cast. To do so, choose a number of wizard spells from your spellbook equal to your Intelligence modifier + your wizard level (minimum of one spell). The spells must be of a level for which you have spell slots.
Nothing says anything about bonus spells slots. I just want to confirm that you do not get bonus spells in 5th edition D&D, right? Because if the chart on page 113 of the PHB says to only choose two 1st level spells to prepare as a 1st-level wizard, what do I follow?
