Log Horizon TRPG/GM EX Powers

The role of the Game Master (GM) is to encourage the TRPG session and provide Player Characters (PC) interesting scenarios. As a result, GM EX Powers are a way for GMs to increase a scenario's difficulty according to the PCs' levels.

(Editor's note: I don't play the TRPG, so this is going to be a direct transcription of the source. I don't know what most of this stuff means.)
