War of the Ring: Lords of Middle-earth

No. Elven Rings cannot change the result of a Keeper Die or Lesser Minion Die; they can only modify standard Action Dice. Each Ring can still be used once per turn for its normal effect, and a Keeper’s special Ring ability is an additional, separate use. (p. 14)

You must choose only one of the rolled Special Die results and discard the others until the next turn. If any rolled Special Die shows an Eye, you must choose an Eye result; that die goes to the Hunt Box. (pp. 7–8)

A Keeper Die is added at the start of the turn after Elrond or Galadriel enters play, or when Gandalf the Grey is the Fellowship’s Guide during the recovery phase. A Lesser Minion Die is added at the start of the turn after the Balrog or Gothmog enters play. (pp. 9–11)

No. When the Sméagol Tile is drawn, Hunt Damage is 0, Sméagol enters play as the Guide, and the tile is removed from the game. Sméagol is not Gollum, so effects referring to Gollum are not affected. (pp. 21–22)

No. The Balrog initially has Level 0 and cannot leave Moria. It must first be activated by choosing its Use Balrog result or by playing “A Balrog is Come!”; while active, it has Level 2 and moves as a non-flying Minion. (p. 24)

Yes, but choosing a result marked with the Remove symbol causes that Lesser Minion Die to be removed during the next Recover Action Dice phase if the Witch-king is in play. The same applies to the Balrog or Gothmog’s die if its associated character has been removed from play. (pp. 11, 24, 26)
