You may place up to two Workers on each Die when resolving an Action; Workers alter the Die by either increasing it to 6 if the Worker and Die share a colour, or by changing the Die’s colour if they differ (up to two Workers per Die only) (pages 8–9).

No — you cannot use two coloured Workers on a single Die to produce a secondary colour; each Die’s colour/value is determined by the single applicable Worker rules (page 9).

Yes — the Deliver sequence requires paying 4 Silver to the Main Supply as step 3 of delivering a Scroll, and you then receive the listed Influence, Gold/White die and Research movement benefits (page 12).

Revealing the bottom Scroll is the first step of Rest: draw and reveal the bottom card of the Scroll draw pile, move the Neutral Marker clockwise a number of spaces equal to that Scroll’s VP (skipping White Spots), then follow the placement/discard rules for the revealed card and the Scroll adjacent to the Neutral Marker (page 16).

When Resting you harvest only the single highest coloured (even-numbered) space your Research Marker has reached (if your marker is on an odd space you harvest the space below it), and any movement beyond level 7 does not move the marker but immediately grants the top-of-track reward (Influence or Gold) shown on that track (pages 13 and 17).

Translating requires only an action that matches the Guild’s colour (value doesn’t matter); you place 1 Gold on each Translator used and must pay 1 Silver to the owner of each opposing Translator (you pay no Silver for your own Translators), while using a Neutral Translator requires paying 1 Silver to the Main Supply (page 14).
