Tea Parties are a bonding activity in Fire Emblem: Three Houses.
Tea Parties are a social activity that Byleth can engage in with the students and faculty of the Officers Academy and staff of Garreg Mach Monastery. While exploring the monastery, the player may approach a character and invite them to tea. Tea parties are also an optional activity on birthdays.
When beginning a tea party, Byleth and their guest will sit at the table and Byleth will be prompted to serve tea. Any kind of tea in their inventory can be offered, but each character has their own favorite and will respond more favorably if it is served. Once the tea is served, the player is prompted to select one of three conversation topics. If it is a topic that interests the guest, they'll respond positively, but they will be disappointed by topics that disinterest them. If the player selects three positively received topics without mistakes, the tea time will extend, and the guest will make a comment, to which Byleth must pick an appropriate response. If a correct response is chosen, the player will score a Perfect Tea Time. Positive resposes will also raise support between Byleth and the guest, but the tea party will end early if too many mistakes are made.
After completing Perfect Tea Time, the player is presented with a menu offering the option to give a gift to the guest, or to observe them. Choosing to observe gives the player the opportunity to examine the guest up close, and the guest will make comments depending on where attention is focused.
Completing a tea party with a Great or Perfect Tea Time grants a permanent Charm boost to both Byleth and their guest.
