Recall

No — all effects on the keycard and the activated action box are optional and may be taken in any order; after resolving any chosen effects, your turn ends (see page 6).

You may use free actions (including ability stones) during a Recall, but once you recharge your ability stones during the Recall you cannot use them again for the remainder of that turn (see page 7).

At the end of your turn you cannot store more than 6 of each type of crystal (white, red, purple) in your storage (see page 8).

Yes — when building you must remove 1 additional follower for each other player that already has a building in that hex, and each of those other players then gains 1 follower into that hex (see page 8).

No — if you move onto or through a hex with a relicube you must remove the required number of followers to pick it up, and if you don't have enough followers you cannot move onto or through that hex (see page 10).

No — when the objective discard step occurs you must discard one of your two objective cards and you immediately receive the reward shown on the lower part of the card you discard; you do not get the reward on the objective you keep (see page 11).
