I ask this question with some trepidation, for you see, I have a player in my group, Fral Leman: Man of Legend, formerly Man of Action, who has done the impossible; on more than three occasions.
It all started during an assassination mission, a planetary governor of a fridge world (with more than it's fair share of lore) has committed so much heresy that the Acolytes are being sent in to take care of it. From stripping the Ecclesiarchy of power to forcing techpriests to commit tech heresies, Gov. Barbarossa Helhand was one evil guy. Skipping several hours of play, the PC's eventually reach Barbarossa in a critical assault after everything goes to hell. Even worse, the governor's palace-fortress is actually the salvaged wreck of a rogue trader ship that is partially functional, elevating the fight several kilometers in the air before a speedy fall. But I digress.
The party, composed of a Biomancer, a Guardsman, and Fral Leman (A guardsman), encounter the governor who turns out to be a lesser daemon in the guise of the governor. Everyone manages to keep their cool but Guardsman A gets blasted out of the armor-glas by a noise blast, sending him off and away. Lucky him, he was still alive and activated his "parachute" (a device I reluctantly accepted him to find). Fral Leman, coming up with his second insane idea of the day (the first to suppressively fire upon over 50 army thugs after stabbing their boss in the throat, detonating their Chimera and killing them all) and takes his two grappling hooks, run at the daemon, hooking onto his leg, running out the window after hooking onto the ledge; and pulling the daemon outside to fall to his doom.
As the ship falls Fral Leman gets back inside while the Biomancer bloats like a balloon and flies away (still surprised that they left him to die). Falling to certain doom, Fral Leman secures himself against the broken control console and lites a Lho-stick on the way down. He is joined by the Prince just before impact (who was essentially a space marine). As he falls he puts on his "Indestructible sunglasses" as the sun sets. I roll Impact damage (5D10 + 5, it is lessened from his secured fastenings). I then proceed to roll: 1, 1, 1…..1…………1!!!! Fral Leman survived a crash that leveled the city while taking only 1 wound.
Mission 1 End
Now before I ever continue on to the more rediculous things that had been accomplished, the Question of the title must be addressed: Should Players be alloowed to change the universe? Namely Fral Leman. A man who has killed everything so far: from Nobz, Chaos Space Marines, Orks and Daemons to Mecha Nobz, a Chaos Lord and a Warp Beast that devoured an entire ship.He even retains a single point of corruption and not a single Insanity Point. This may seem like endearment but if you had seen the things Fral Leman has done in-game, I can't help but wonder what he ISN'T capable of (which kinda scares me a a GM). I have thrown almost anything and everything I had. The only thing that the player admits that Fral Leman wouldn't do well at is investigation. Although, he does say that, and I quote, "Fral is all about getting **** done, no excuses, no fears." I could talk much longer about what Fral has done but I must keep this about the post question.
Note: currently Fral Leman has attracted the attention of several Inquisitors for investigation based on his deeds (considering he is only a regular former guardsman turned mercenary).
