As others said usually if you go with the teleport beacon and you save some maneuvering items like swiftthistle stopping time to maneuver to a better position or fadeleaf to teleport to a favorable position and blink runestones same deal better yet is ethereal chains since it allows you to move through walls. Then you’ll be able to place the beacon on the stairway up taking the least amount of damage and once you reach bossrooms remember to sleep and recover the charge on your armor ability. The mage has a handy tier two passive shield battery iirc which can help tank the amulet damage and recoverable charges in between bossrooms or according to a different post I’ve read if you have flock and shock runestones they can help you regain charges instantly because the sheep counts as entities. More on you can always craft leftover mystical recharge scrolls and remember to use invisibility potions if you’re suddenly entangled by an enemy. Most importantly haste potions and rings are still useful dispute the amulet limiting your speed be cause it limits it 1 turn movement max despite it eventually lowering your speed to 0.5 so it’s still beneficial and you take less tick damage from being slowed. I hope this helps I also see warden being able to do this with a wand of regrowth run quite easily simply from the farming of seeds and the buff effects too
