Can I add an action speed card to the chain if the last card added was an action speed card?

Question

Accepted Answer

No, you cannot add an Action speed card to a chain if there is already a card on the chain.

According to **RiftJudge FAQ #2855**: "Only reaction cards can be played in response to action cards. Action cards cannot be played in response to other action cards."

Furthermore, **RiftJudge FAQ #4042** clarifies that "Actions can only start chains... They cannot be played while there is already a chain in progress."

### Key Rules for Timing:
*   **Action Cards:** Can only be played to *start* a chain when the game state is "Open" (i.e., no chain currently exists).
*   **Reaction Cards:** Can be played to start a chain OR added to an existing chain (in response to other cards or effects).
*   **Chain Progression:** Once an Action card is played to start a chain, the state becomes "Closed." While the chain is active, only Reaction cards may be added to it. You must wait for the current chain to resolve completely before you can play another Action card to start a new chain.
