You touch a willing creature; they sprout 8 spider legs from their back. The creature gains a climbing speed of 60 feet and can climb vertical surfaces and along ceilings without needing to make a skill check. The target gians access to the “Web” spell which they can cast once, using your spellcasting ability. The target gains a special action “create webbing” which allows them to use their action to roll a d6, the result corresponds to a number of 5ft tiles the affected creature can coat with webbing, each coated tile must be within 20 feet of them. The webbing has an AC of 10, 5hp, vulnerability to fire damage, resistance to blugeoning damage, and immunity to psychic and poison damage. Any creature that isn’t affected by this spell, or doesn’t have the Web-Walking trait, treats it like difficult terrain.
