A Martial at the highest tier breaking an iron door into splinters then using the splinters to rig stairs, can be fun.Taken far enough, yes. Some warriors can literally fight for days on end. This implies some sort of temporary hit point ablative system, being able to shrug off exhaustion, etc. A warrior might be able to take a normal sword and split open an iron door into ribbons, then drive the shards into the wall to make stairs. A rogue might instead be able to pick a lock that jams a trap with a crossbow bolt from thirty feet away while dangling upside down.
That said, a caster can cast Knock (or more likely use a skill to unlock door), and cast Spider Climb or Levitate at the lowest tier.
