The thread about MR got me thinking - what are the various ploys used to evaluate loopholes in the MR rules? Whether they work or don't in the new edition.
Here are a few I could think of -
Pebble of Crushing - send a boulder diminished to pebble-size to hit a magus. If the diminishing effect is dispelled, the magus would be crushed by it.
Tree in Sheep's Clothing - transform a tree into a sheep and let the dragon swallow it. When the spell ends, the tree bursts him from inside. Glass of Betrayal is the magus variant - poison turned to wine.
Pink Dotted Sword - wizard casts spell to paint dots on sword, if MR stops item (as it does in the RAW) he is now immune to it.
Magi's Fist - a wizard under an ongoing magical effect (e.g. a longevity ritual, or a MuCo(An) spell) punches another. Is the fellow immune to the hit? RAW says not, but pretty arbitrarily.
Excalibur - is a magical sword more penetrating than a plain one? Not according to the RAW.
Pilum of Fire - nearly any parma variant resists this, of course.
The Pit - make the ground below the target go "poof". Does he resist?
Pit & Cover - make the deep pit below the target, watch the target fall, then immediately create or move a ton of earth above the pit and laugh maniacally as it naturally falls down on top of your enemy. Does the magus get to resist, at any point, and how does that appear?
The Anvil - levitate an anvil above the target, then let the magic lapse. When the anvil falls on the target, does it resist?
Engulfing Rock - create a rock just around the target, immobilizing it. Does it resist? And how does that manifest if it does?
Treacherous Prize - give a gift of a magical item to a magus. If MR needs to be suppressed when he picks it up to accept it, the secret effect goes off without any resistance.
Sling - you throw a nearby boulder at your opponent magically, does he resist?
Fall on Bridge - magus falls on magical bridge, does the bridge dissipate?
Bridge Falls Down - magical bridge falls on magus, does the magus resist being squashed?
Fall on Spikes - magus falls on magical spikes, does he resist getting damage? Just damage from the magic?
I'm sure I'm forgetting a lot.
