I haven’t really had issues with that trap, and they seem to only begin to appear during the caves. There’s a number of things you can do to deal with a pitfall trap once you’ve activated it:

• potion of levitation
• stone of teleport
• spell of feather fall
• hour glass
• chains
• scroll of teleportation
• the enhanced scroll of teleportation
• the special spell that allows you to teleport, but also be stunned (forgot the name).
• wand of repulsion (assuming a sufficient enough level)

Other things you can do to minimize damage:

• Healing potion (ignoring if you have pharmacopoeia)
• Potions of shielding (ignoring if you have pharmacopoeia)
• cleansing potion (to remove the bleed damage after the fall)
• The purity related seed (to remove the bleed damage, and assuming seeds work for your run)
• Any shielding ability from talents or sub class talents.

I’m uncertain whether I’ve died to the trap because usually i likely have a potion of levitation, feather fall, or any teleportation based items. I usually play with at least 6 challenges, but more recently with 9 challenges. I’ve played at least 700 runs, maybe 1,000 (switched phones several times)

What were the circumstances of your deaths?
