No, you must have at least 1 Influence with the faction controlling a board space to place an Agent there. If you don't have the required Influence, you cannot use that space even if you have the right cards to pay for it.

Once a Tech tile stack is depleted, no new tiles are added to that space. Players can only acquire Tech tiles from stacks that still have face-up tiles available. The game continues normally even if all stacks are empty.

Yes, each 'Acquire Tech' icon allows you to take one Tech tile. If you trigger multiple icons in the same turn (from different cards or board spaces), you can acquire multiple Tech tiles, choosing from any of the available face-up tiles.

Dreadnoughts and regular troops fight in the same Conflict and their Combat values are added together. However, some Conflict cards may have different rewards or requirements specifically for Dreadnoughts versus regular troops.

You receive the Freighter bonus immediately when you advance it on the Shipping track, not during the Makers phase. The Shipping track provides instant benefits when your Freighter moves up.

Most Intrigue cards can only be played during specific timing windows as indicated on the card (such as 'Combat' or 'Any time'). Strategy Intrigue cards are typically played immediately when drawn or acquired, while others have specific trigger conditions.

You cannot place your Agent on a board space if you cannot pay its full cost in Spice, Solari, or other required resources. You must be able to afford the entire cost at the time of placement, even if the space would give you resources back.

Yes, ongoing abilities from Tech tiles stack with similar abilities from other Tech tiles, Leader abilities, or card effects unless specifically stated otherwise. Each source of the ability applies independently.
