I ' ve been working my way through the dwarrodelf cycle progression style and plowed through Khazaddum two handed . The first quest is fairly questlocation heavy but the next two have tons of weak 2 hp Orcs with the occasional beefy troll . I found Thalin to be really good on these quests because of that , he and a gondor Spearman or long beard orc slayer could decimate most enemies on the board . Gimli came along to take down the beefy guys . I ' ve only used tri sphere once so far on road to Rivendell , along with mini spirit . It worked fairly well , but you really have to factor in your resources in terms of what cards to include . I don ' t think you need every sphere , but I ' ve found tactics to be the least essential so far except on certain quests .
