Once inside, should a player have at least level 95 in all other non-elite skills, they may put their arm into the Maw and retrieve a random treasure once per day. Otherwise they will receive a message stating the required levels to access the Maw. Rewards include a range of items, some of which can be useful in helping players complete requirements for the regular and trimmed Completionist cape, as well as for the Master quest cape.
Rewards received are weighted towards requirements which have not been completed by the player, but it is still possible to get items towards requirements that players have already met. Additionally, players may once per day exchange with Wythien 10 motherlode shards, for potential rewards similar to those given by the Maw.

Prior to the release of Invention, the Maw had required a total level of 2490 to access. This was later changed a little bit after Invention was released, then requiring a total level of 2585 to access the Maw. This was once again changed, in a hidden update on 5 June 2017 to require certain levels in individual skills.
Air and fire runes can be used on the Motherlode Maw to get responses from it.
Using an air rune on the Maw will give the player an ancient air rune with the text "The maw gives out a gust of wind, whatever was in there is now no longer present."
Using a fire rune on the Maw will produce the text "The maw crackles with flame, as the night is dark and full of terrors..."
Using a Ring of Kinship on the Maw will prompt a message saying: "The maw rejects the Ring of Kinship and rejects your offer to party. Don't you feel silly now?"
The Motherlode Maw received a generous reward overhaul in a game update on 4 September2017, as the result of an effort pioneered by Mod Meadows. The initiative to reform the Motherlode Maw's rewards was first announced to the community in a forum post by Mod Meadows on 25 May2017, which contained numerous design suggestions and polls to gauge player feedback on the proposed reward changes.
