TLDR: What can I do when a player is getting upset by low rolls causing poor PC performance?
I'm running a duet gestalt Pathfinder campaign in Roll20 with an Incanter/Conscript (from the Spheres).
Issue I'm running into is my player seems to be getting alarmingly discouraged in response to any sort of low rolling. For example, last session, against a single enemy, combat went something like this (Level-3 Gestalt PC vs level-3 Warrior; a nat 10 was needed to hit enemy AC, with the -2 from attacking twice):
- PC: Nat 2 on stealth, initiates combat. Wins initiative. Attacks twice, with nat 5 and nat 12.
- Enemy: Attacks, hits. Takes off ~20% of PC's hp.
- PC: Nat 1 on acrobatics to move without provoking (enemy misses), attacks twice with nat 8 and nat 16.
At this point, the player was getting upset, so I just lowered the enemy's AC by 2, which was enough to down him.
Despite what I view as a rather one-sided victory by the PC, the player was upset by the PC's apparently poor performance. The player complained of it seeming as if s/he always rolled low while I always rolled high - and admitted that, while this view may be due to confirmation bias, it was still distressing.
The player then proceeded to mention that a portion of the issue is that there is no 'get up method' - that, due to the nature of the solo campaign, if the PC dies, that's the end. At this point I mentioned that there was actually a planned plot device to undo character death, but I don't know if that helped anything.
Obviously, the first suggestion would be 'talk to the player', but I've already done that - s/he replied that 'It's my fault; I should have built {PC} better." I don't actually agree with this assessment - while the PC isn't hyper-optimized or anything, the build isn't bad. And even if it were, it's my responsibility as GM to make appropriate-difficulty challenges.
The problem is, how do I do that when a nat 5 failing is seen as problematic? I could make things massively easier (or just lower AC to basically nothing while upping hit points to maintain difficulty?), but I'm not sure what actual point there would be to combat, at that point.
