Solak

Solak, the Grove Guardian is one of the Guardians of Guthix and can be fought at The Lost Grove. He is deemed as one of the strongest bosses in-game, with 8 million life points. His drops include tier 92 dual-wield blightbound crossbows, the strongest crossbows in the game.

During the fight players fight alongside Merethiel, who plays a significant role in the lore behind Solak.

There is a hard cap of seven players to fight Solak, though there is also a duo mode, which is similar to the standard fight but the mechanics are changed to accommodate for the smaller team size.

Defeating Solak is required for The Reaper title which remains required for the completionist cape. Solak is a requirement for the Final Boss and Insane Final Boss titles. The title is achieved from obtaining all drops from Solak's collection log.

History
Solak is a creature of the Anima Mundi, like Vorago and Telos, and a Guardian of Guthix who defends the Lost Grove from those who want its power. He is referred by the inhabitants of the grove as a "Walker".

Solak was tasked in protecting an island that is inhabited by smaller creatures of the Anima Mundi. During the Second Age, Seren sent four elite elf warriors to aid Solak in his task. However, one of these elves, Erethdor, became tempted by the power of the grove and attacked Solak in an attempt to control it. The fairy Bub thinks of the elf as pure darkness. Erethdor was defeated through the combined efforts of Solak and his siblings, sealing half of his mind within Solak himself and the other half within a stone in Merethiel's possession.

After this battle, Solak knew that he was "broken" and told the elves to leave and inform Seren of Erethdor's betrayal. He then sealed the grove, knowing that he could not let Erethdor use it at his own will. The fairies tried everything to contact him, along with humans building temples to worship him; however, the religion died out as he never responded. The grove would not be in contact with the outside world until the fifth year of the Sixth Age. By this time, Erethdor had completely corrupted Solak, with the Guardian being mentally weak and unable to resist him after thousands of years of keeping him at bay.

Drops
