Vine Trestle

You cause a vine to sprout from the ground and crawl across a surface or rise into the air in a direction chosen by you. The vine must sprout from a solid surface (such as the ground or a wall), and it is strong enough to support 600 pounds of weight along its entire length, which can be a number of feet up to 5 x your spellcasting level. The vine collapses immediately if that 600-pound limit is exceeded. A vine that collapses from weight or damage instantly disintegrates.
The vine has many small shoots, so it can be climbed with a successful DC 5 Strength (Athletics) check. It has AC 8, hit points equal to 5 × your spellcasting level, and a damage
threshold of 5.

Group Spellcasting. When other spellcasters aid you in casting this spell, the vine can support an additional 30 pounds, and its damage threshold increases by 1 for each spellcaster other than yourself, supporting up to a maximum of 810 pounds with a maximum damage threshold of 12.  When the primary caster casts the spell, each aiding caster must expend a 1st or higher spell slot during the ritual, though only the primary caster needs to have the elven ritual spell on their spell list. An aiding caster can be of any level, so long as the aiding caster can cast spells of 1st level or higher. Casters that can’t normally cast ritual spells, such as sorcerers and paladins, can still aid the primary caster.

Ritual Focus. If you expend your ritual focus, the vine is permanent until destroyed or dispelled. To expend a ritual focus, pay twice the cost of the material component in the ritual. This might represent the material component’s construction of higher-quality materials, or it might simply mean using more of the listed material component, whichever is most appropriate. If a ritual’s material component normally does not cost any gold, to expend its ritual focus, spend 100 gp.
