Tekhenu: Obelisk of the Sun

No — on your turn you may only take Pure or Tainted dice, not Forbidden (page 10). The sole exception is spending exactly 2 Scribes to perform an Anubis Action, which lets you take any die (including Forbidden) and use it normally (page 14).

You may spend one or more Scribes to adjust the value of the die (values cannot go below 1 or above 6), and spending exactly 2 Scribes performs an Anubis Action; you may combine these effects (for example, spend 3 Scribes to take an Anubis Action and also adjust the die) (page 14).

Any excess resources are placed on the right (Tainted) side of your scales as Taint, they cannot be spent, and each excess resource counts as −1 when resolving your Maat balance (pages 21 and 11–12).

The Obelisk rotates one section clockwise every two rounds (this occurs when players have exactly 2 or exactly 4 dice on their boards); during Rotation you roll and add dice into the two Shaded sections, ensure all dice are placed into the correct Pure/Tainted/Forbidden rows, and if players have 4 dice you immediately perform a Maat phase (page 11).

Gray dice are always Tainted (never Pure or Forbidden) and gray dice cannot be used to Perform the Produce Resources action (pages 9 and 21).

When you raise a Pillar you score 1 VP per Building in the same row and column and 1 VP for each matching edge color on the Pillar tile (if you place the Pillar in a corner, each matching edge scores 2 VP instead of 1); you also receive the reward shown on the covered space and VPs for the space from which the Pillar tile came, then place a Pillar to mark ownership (page 17).
