Barbarian
Battlerager is allowed for Dwarves. New totems are allowed as well (SCAG).
Cleric
Domains and Deities
Zeus - Tempest, Life
Hera - Trickery, Knowledge
Poseidon - Tempest, Light
Demeter - Nature, Life
Athena - Knowledge, War
Apollo - Light (Clerics of Apollo are exceedingly rare, as he calls his heroes to be Paladins primarily *needs GM approval*)
Artemis - Nature (Also rarer, as many of Artemis's chosen become Druids or Rangers)
Ares - War, Trickery
Aphrodite - Trickery, Life, Nature
Hephaestus - War, Light
Hermes - Trickery, Life
Dionysus - Nature, Knowledge
Any of the other minor deities or non Olympians may be chosen as a deity as well (Eros, Persephone, Hades, etc). We will work out which domain a cleric would fall under during the process of character approval. Hecate would fall under the Arcane domain in SCAG, for example.
Druid
Druidic magic seemingly comes from Artemis and Demeter.
Fighter
Purple Dragon Knight is a choice for Larendarian characters- retitled as Bannaret (SCAG). You are in essence a landed knight of Larendar.
Monk
Monks are not a playable class, as only Veshi understand and have undergone such monastic training required to possess their talents.
Paladin
99% of Paladins receive their power from Apollo, and all Paladins of Apollo take the Oath of Devotion or Oath of the Crown from SCAG. Oath of the Ancients and Vengeance may be taken as well, as Paladins of Artemis, but these Paladins are exceedingly rare *needs GM approval*
Ranger
Like Druid spellcasting, a Ranger's magic is also tied to their closeness with Artemis and Demeter.
Rogue
Mastermind and Swashbuckler are allowed (SCAG).
Sorcerer
Storm Sorcerer is allowed. Your power would theoretically come from a monster tied to the air or land, such as Scylla or Charybdis.
Warlock
For Warlocks, the source of the power that comes from their Otherworldly Patron is a large mystery. It could be beings from another plane, old gods from before the Upheaval War, or something far worse...
The Undying are allowed. Your power is tied to a cult or a powerful lich (SCAG).
Wizard
Bladesinger is allowed for Elves and Half Elves (SCAG).
