Climbing rope, Entanglement rope, Web rope.
eg: dwarf cleric with no feather fall, can't make the jump? No worries, just get out your Rope of Climbing.
eg: Druid/ Ranger spell, cast the entanglement rope around one creature.
eg: Druid/ Ranger spell, cast Rope of Web around multiple targets.
I come up with the ideas, you math people apply the numbers.
