You've no doubt noticed the'scavenging the OSRS Gold
battle for loot' message, and you've probably picked up several pieces of gear already. Loot in RS matters, it is not just decorative, with some exceptions.
Since the bits of gear that you equip can and will have an effect on your heart stats, the developers disabled equipment effects in 1v1 Duel, and 2v2 Brawl manners. Only the 4v4 Dominion will take into account the effects your gear has.
Bearing that in mind, it's worth paying attention to what you have outfitted before a Dominion match. The match will automatically compare the item you're inspecting together with what your hero has on at the time, so consider your options and spec on your favorite playstyle.
The more useless gear you Buy RS Gold
scavenge, the longer stuff you are going to need to upgrade the pieces you care about.
