Looking at other questions about casting spells as a bonus action has left me trying to keep a lot of information in my head about whether a given combination of spells is legal according to the official 5th edition spellcasting rules.
So I'd like to consolidate all these rules into a single easily accessible table, containing all the possible combinations of spells that could possibly be cast in a single turn, and hopefully create an easy reference for future use. But I'm not certain about how some of these combinations should be treated.
Based on the second question I linked, the ordering doesn't matter, so I've simplified the chart to ignore order of these actions, and only focus on what actions are being taken. But if I'm mistaken (i.e. the answer provided to that question was wrong) then this table will need adjusting.
|Action||Bonus Action||Action Surge||LEGAL?|
Is this table (Column 4 in particular) correct?
The core issue for me is that it's not clear to me how Action Surges interact with the spellcasting rules, hence the question marks listed there. It seems like an Action Surge might permit 2 leveled spells to be cast in a turn, unless a Bonus Action is used to cast a spell, in which case this is no longer permitted. If this is correct, then my table above should be correct, minus the question marks. But I need that validated.
