My Time at Portia Wiki

Isaac loves philosophy. He feels that in an age where critical thinking is lacking, he is a lone rock standing against the anarchy of chaos. An avid reader of books, Isaac wants to complete his own magnum opus, "The Oral History of the Age of Darkness" before his time's up.

Isaac is a resident of Portia with whom the player can develop a friendship. He is a longtime resident of Portia. One can find him in the park near the slide in the center of the town and he invites players to play Cross Five with him. He enjoys books, being left alone, Cross Five, and being overly protective to his books. He is not formally employed, though he does function as the town's sole representative of the debt agency.

Isaac can be found throughout the day in the playground with a stones board and is always up for a game of stones.

Personal life[]

Isaac was born on Winter of Day 16 and is one of the oldest residents of Portia. He philosophizes that in the age where critical thinking is lacking, he is the only one left that has the knowledge and thinking of the old world. An avid reader of books, Isaac wants to finish his own magnum opus, "The Oral History of the Age of Darkness". He hates gatherings, but according to Polly, he secretly loves the Winter Solstice holiday.

Isaac loves to play Cross Five in the playground, a game where critical thinking and skills are needed to defeat the opponent. When he is not playing, he can be found either meditating or reading books in the Commerce Guild.

Physical appearance[]

Isaac is bald, except for a patch of white hair above his ears. He has a white goatee on his chin, a long and pointy nose, tiny blue eyes and wears a blue waistcoat with a white handkerchief, a long long-sleeved shirt with beige stripes (which extends way down over his thighs) and brown trousers and shoes.

Chat is a basic social interaction available at any relationship level. Chatting with Isaac once a day can increase his relationship by 1 point, or 2 points with the Smooth Talk skill; subsequent chatting, on the same day, only results in the same conversation without any relationship gain.

Isaac's dialogue may change every day and every season. Isaac may also comment about certain events or missions. Higher relationship levels also change Isaac's dialogue.

  • Every giftable item, except for the items below, will have a Neutral (+1) effect when given to Isaac.
  • Gifts given on festival days and on Isaac's birthday will earn the player 2x and 3x relationship points, respectively, and will show a unique dialogue.

Desires[]

The following items are desires, or wishes, which are randomly assigned to one or two characters per week. The player is required to be at least at Associate level with Isaac for him to be assigned a desire. More desires have a chance to appear as the player's friendship with Isaac progresses; the new desires are added to the existing ones but do not replace them. Some characters may desire an item that they do not normally like.

In the event that Isaac has a desire, gifting the wanted item will provide the higher tier points; otherwise, on non-desired events, the item gives the base point value. The birthday or festival day relationship bonus applies when gifting a desired item.

Isaac will place the Hardwood Sofa or the Tea Table inside his house if he receives them when desired. verify ]

Relic trade[]

Isaac occasionally uses the Relic Pieces Exchange board at the Museum to trade for relic pieces. Isaac likes to look at particular completed relics, so after the player has donated such relics to the Museum or displayed them in their yard, Isaac may come visit the Museum or the player's yard to view these relics. Such visits will earn the player relationship points each time, with the amount dependent upon the relic.
