The exact conditions behind their style and prayer switching, the boulder, and their drop table.
Demonic gorillas are combat 275 with 380 hitpoints and a max hit of 31 in every style. They switch their attack style and their protection prayer during the fight, so they punish autopilot harder than anything else.
