Isis/Strategy

Isis' bonuses are very broad, leaving the player with a lot of scope to develop their own strategy.

Strengths
All technologies are cheaper, making savings across the board, but especially with the military since Egyptian units are upgraded individually. Isis' god power and myth technology are also economic as they provide extra gold and food respectively. Isis' Town Centers provide +3 population, allowing for either a larger army or labor pool.

One of Isis' most formidable powers is that Monuments cancel out god powers, within a wide radius. If an Isis player's monuments are spaced out properly, opponents will not be able to use any god powers in her territory, hampering their attacks. For scouting, Isis players mostly have to rely on the Priest, who is poor at this job. However, her Obelisks are cheaper and are summoned much more quickly than those of other Egyptian civilizations, which helps to offset this a little.

Unlike Ra, Isis has access to Nephthys as a minor god as well as Osiris. If both are worshiped and players research the City of the Dead myth technology, their Son of Osiris will receive a significant boost in HP, making it one of the most powerful hero units in the game.

Weaknesses
Of the three Egyptian major gods, Isis is the only one who does not provide military bonuses. Therefore, players will have to rely on regular technologies or myth technologies provided by her minor god roster to improve their military units. Other than that, Isis simply has the typical weaknesses of an Egyptian civilization such as Laborers that build slowly and the need to upgrade military units individually.
