This is an anecdote.
We had a situation late in our last session where our troupe was trying to unexpectedly transport wagons up a valley towards home base, but they had to get past a narrow chokepoint, wide enough for a single horse with rider to squeeze through or a person with a wheelbarrow. It was rather important that they could not damage the bare-stone valley walls forming the chokepoint.
So after some discussion (including things like how to shrink the wagons) I acknowledged that higher up (just above the horse rider) the chokepoint widened out. So the troupe decided to lighten the wagons (including removing the wheels) and multicast âThe Unseen Porterâ ReTe 10 to carry the wagons over (targeting the metal brackets holding the axles), about 10 feet above the ground.
Then somebody reading the spell description pointed out that the Unseen Porter could only lift things only 6 feet high. The troupe immediately acclaimed that the unseen porter was some sort of spiritual entity only 6 feet tall, and needed to walk on the ground, even though it was intangible and invisible.
Then came the attempts to build a ramp. When the Merinita mage asked if an illusory ramp would help? After some discussion I allowed that an illusory ramp that includes a sensation of touch might work if the casting sigil of the casters of the âUnseen Porterâ didnât break the illusion of the ramp.
One casterâs sigil was âsunlightâ, meaning the carried wagon would not put an illusion breaking non-shadow on the ramp. The other casterâs was âa sense of Homeâ, so I ruled that since the direction was towards home base it succeeded, if the direction had not been towards home then it would have failed.
And a thus good time was had by the players doing a lot of sponting and spell casting.
