Petra also has bounties for the Guardian to eliminate other high-ranking members of the Wolves, including a mission to kill the Archon-Slayer Skoriks. Variks has the Guardian to complete the strike "The Shadow Thief" to eliminate Taniks, the Scarred, a mercenary for hire among the Fallen who is employed by the Wolves but does not belong to any House. In the base game, there is a story mission called "Scourge of Winter" where the Guardian is tasked with killing Draksis, Winter's Kell. When "The Taken King" released, it added a new questing system to the game and this mission became the first mission of the "House of Wolves" quest line. "House of Wolves" received better reception than its predecessor, "The Dark Below". It has an aggregate score of 72/100 for the PlayStation 4 version (based on 31 reviews) and 71/100 for the Xbox One version (based on 4 reviews) from Metacritic—no score is available for the PlayStation 3 and Xbox 360 versions. Jose Otero of IGN, who gave it a 7.5/10, said that the expansion "learns from its predecessor's mistakes." Although it did not fix "Destiny"s issues with the story or its loot system, "it does introduce new, sensible gear upgrade paths, a fun new campaign with a few surprises, and rewarding endgame activities". There was less grinding as gear dropped at higher levels than previously, however, this only applied to "House of Wolves" gear. The new Etheric Light material was praised, as it let all previous legendary gear be upgraded to the new stats without having to relevel the gear, although the material was a rare drop. The Prison of Elders PvE arena was praised, but Otero said that there was not a lot of variety in its objectives. He said that although it was not as impressive as a raid, "it's unique enough to stand on its own merits." Trials of Osiris was also praised. Martin Robinson of "Eurogamer" had similar remarks and said the expansion "deliver[s] an overhaul of systems and a stream of modes and features that are the best thing to happen to "Destiny" since its launch." He said it felt like Bungie remembered what made their previous games so special. Robinson highly praised the new sidearm weapon, calling it one of Bungie's best guns on par with pistols in their previous "Halo" games. The new level cap was praised for being easier to obtain than previously.
