I don't know whether that's already a known thing, or whether that's even useful in any capacity. But I've managed to clear the cube maze without any encounters - including skipping the Anubis at the end to get the Mirror Shield

What you do is: Aggro the boss flame -> quickly move behind one of the pillars on the side -> wait until the boss flame goes back, and then simply run past it

Probably not terribly useful for the cube, unless an all-bosses run would include a strategy to use the Mirror Shield, but I figured this may have applications in other places

I also skipped the boss on the beach, that guards the Shaman crystal with some clever jumping, drowning the boss flame
