I feel like you're having too much fun with the mindspace thing,Kilga :V
An idea I had that you could try?next time we're safe, is try something that technically doesn't exist ("lightweight petal-cutting-proof umbrella" for example) or either something entirely abstract ("the solution to this entire situation", although I'm fairly sure Purvis would shut this one down immediately :V)
If nothing else, maybe you can use the mindspace for actions rather than just summoning things, like, say, "Cut the tree in half" although, again, I'm pretty surepurvissaw that coming already, still, food for thought, just in case I miss another 4 pages like the past few days.
