I should have posted this earlier, since it's mostly Channeling (with some Mentalism), but in the interest of contributing something...
The party is in the heart of the enemy's mountain fortress, where we have found the fabled Tree of Life, stolen ages ago by the fabled sorcerer, Yatic, who appears to be in the process of returning. We were kind of hoping the Tree would be smaller, maybe "tree" is a metaphor and it's actually a nice compact piece of jewelry? No such luck. It's at least 400' tall with enormous roots that extend out over at least a square mile on the ground. Magic reveals the tree is or contains a powerful spirit: definitely what we are looking for. The leaves are of all types, as if it is All Trees. But the outer bark seems to be burned and the leaves all seem to be diseased. The air is thick with red mist: blood. We have to tie damp cloths over our mouths to filter it out. There is blood everywhere, like dew condensing out of the air. All meant to corrupt the tree and change its nature. Obviously we can't move the tree, but we suppose maybe we can get some kind of seed or cutting.
My character Niles, a Nightblade, has boots and gloves of spider-climbing, so I climb the tree looking for seeds or pods (none are visible at ground level). The tree is slippery with blood but that's no problem for the spell so I keep climbing higher, looking for anything promising.
Meanwhile Nilda, the Animist, tries to take a cutting. The first one crumbles to dust in her hand after a second or two. Thinking the corruption is the cause, she tries a disease purification spell as she takes another cutting; it lingers about a minute, then blackens and crumbles to dust. Better, still not a success. Did I mention this is Nilda's player's first Rolemaster game ever? But she's not willing to give up. She uses disease purification followed by a preservation spell on the third cutting: again it lasts about a minute, then crumbles to dust. Almost defeated, she says she will try one more thing. Disease purification, takes the cutting, and then quickly casts a Lifekeeping spell to try to keep the spirit in it. Can't hurt, right?
This time the cutting doesn't turn to dust.
This time the cutting remains and the entire remainder of the 400' tree turns to dust.
At this point, I am about 350’ up the tree which has turned to dust. My Landing spell makes me perfectly safe... for a fall up to 120'. Acrobatics... adrenal landing... add it all up, it's not enough. But the roll is a natural 100 and Niles will live to climb another tree (hopefully with less blood).
After that there are the wyverns and the lesser black reavers, a desperate 100' climb to a platform with a magical circle we use to Gate out just in time... and then what the heck do we do with this cutting anyway?
The GM has no clue either, he never expected us to actually take the tree with us, only to report back where it was. But a clever set of spells (and matching good rolls) and the game has gone somewhere none of us quite expected.
