you cant intimidate or be intimidated by yells someone who scarier/less scary than you
Some way of decreasing the impact of Yell would be good, I was thinking Resolve, but Resolve is also a stat almost nobody cares about because only Will and your level increase it, and Will is nearly only ever used for psi builds (the other few times are very specific builds making use of Ripper, Stoicism or Fight Response) that aren't affected by Yell. I kinda wish Yell also messed with psi casting, something like worsening concentration and thus weakening the resulting spell, with a lesser Intimidation impact than on regular weapon usage.
Speaking of, I also wish you could avoid Body Horror while (
mercy-killing the mutated lemurian), akin to closing your eyes and resisting the temptation of opening them, but it's been a while since I've done that quest so maybe it's already an option?
