Use Entry Mode, learner teams, or low invocation to recognize every room before adding pressure.
Build the raid, not just the bank.
Choose a raid to compare entry, balanced, and high-end gear paths, then follow the inventory, room, and role guide that matches how you actually play.

Tombs of Amascut
Build a flexible three-style setup, learn each path at low invocation, and raise raid level only after the Wardens feel controlled.

Chambers of Xeric
Learn flexible room scouting, prep only what the team needs, and build toward a clean Great Olm cycle with a gear path that fits solo or team play.

Theatre of Blood
Use Entry Mode to learn the room language, graduate to a role-based Normal Mode setup, and invest in melee damage only after the team mechanics are dependable.
Balanced, Bowfa, dragonbane, melee, and role-specific routes all have different inventory costs.
Fix the weapon or role that slows the whole raid before buying minor armour switches.
