Earthen root Enclave Trifecta run (No death, Speed-run, HM on all boses). Run starts when we engage the first group of enemies (so probably 16:42 then) which is the achivement description for speed run in the game:

"Defeat all encounters in addition to the Corruption of Stone, Corruption of Root, and Archdruid Devyric within 25 minutes of entering Veteran Earthen Root Enclave. Your timer starts when you engage the first group of enemies."
