The appropriate modal to complete the sentence is: ought to

The complete sentence is: "The party was very entertaining; you ought to have been there."

Here's why:

"Ought to" expresses obligation or strong recommendation. It suggests that the speaker believes the listener would have enjoyed the party if they had attended.
"Need to" implies necessity or requirement. It doesn't fit the context as attending the party wasn't mandatory.
"Dare to" suggests a challenge or risk involved, which is not relevant in this context.
"Used to" refers to past habits or actions. It doesn't fit the present-tense context of the sentence.

Therefore, "ought to" accurately conveys the speaker's strong belief that the listener would have enjoyed the party if they had been present.
