I was running an endboss solo encounter for my group, a pirate captain who felt the treasure they were after really belonged to him.
I set up a three stage encounter with him using stealth, then melee weapons with it ending with him displaying some force powers to really give them a challenge.
after two rounds, one of the players crits him and through dual wielding and specialization tree stuff adds 100 to his crit roll, killing the endboss in one hit and ending the encounter I'd taken some time setting up.
Some of this is my fault in that an oversight on my part allowed this player to get crit 1 on both of his enhanced vibroswords. A couple of ridiculously high rolls by their weapons mechanic gave them extra hardpoints to put all of the extra modifiers on. I used some destiny points and other stuff to keep the boss from dying so he could at least try to use some of the force powers, but he was easily killed by the next hit before he could act.
I don't begrudge my players the kill, I wanted them to kill him, that was the point of the encounter, but them killing him this easily, and in a way that skipped most of the encounter annoys me a bit. I could be a jerk and just break his sword the next time he rolls a despair, but that feels a bit cheap. I don't mind him one hitting minions or even a couple of rivals, if they're important enough later I can always resurrect or whatever, but if I'm setting up an elaborate bossfight, I'd like it to take them a bit longer.
Any tips you guys might give me?
