The short version
30-second read- Only 5 of 97 bosses have no gate. Scurrius, the Giant Mole, Sarachnis and the Royal Titans are among them, so combat stats are the only check.
- Raid unlocks open the most bosses. Chambers of Xeric and Theatre of Blood gate six entries each, and Tombs of Amascut gates five.
- One quest can open four bosses at once. Desert Treasure II gates Duke Sucellus, The Leviathan, The Whisperer and Vardorvis, so check clusters before you plan.
- Brutus is the entry point, TzKal-Zuk the ceiling. Difficulty runs from 1 to 5 across the 97 entries, starting at the Cow Boss and ending at the Inferno.
Overview: Every Boss Requirement in One Table
Of the 97 bosses in our index, 92 sit behind a quest, Slayer level or area unlock and 5 can be fought as soon as you can survive them. This page is the full list, grouped so you can clear several gates in one trip instead of discovering them one boss at a time.
The pattern worth noticing: the expensive requirements cluster. Finishing one questline usually opens several bosses at once, which is why checking this table before you start is cheaper than checking it per boss.
