yeah, try to sneak attack enemies if they get alarmed when they see a corpse of an enemy killed by a player, good luck with that. When enemies get alarmed, they start searching for you and the game AI will always move them in the direction of the player without hesitation, which is just stupid, cause they dont know exactly where you are if you used a silenced weapon. but they always find me. If I can ensure 100% critical, I can continue shooting them even if they are alarmed. Won't work on enemies with high DT, but will work on average enemies, standard non-sneak criticals will still kill them.
Now since you mentioned the Boone quest above, have you noticed that the pickpocket trick I described works on him as well? You can pickpocket his beret as well, same as with Manny, which will not break his quest, but is confusing to the player, because Boone will still give you his beret, even if you pickpocketed it from him before. As with all quests in this game, this quest is extremely buggy, I actually went ahead and re-wrote all 3 scripts that govern this quest and all AI packages from scratch, because everything is so broken and buggy on this quest, it simply cannot be fixed, Obsidian's scripting sux. Now if the player tries the reverse-pickpocket trick on Boone, it won't work any longer, if Boone notices that the player is trying to exploit this glitch, he will immediately re-equip his beret, comment on this and knock down the player, similarly to the Victory Rifle in F3. It's extremely funny, my sniperess nearly fell off the dinasour when Boone knocked her down, hahaha!
Also, after testing the Light Touch perk, it turns out it doesnt work properly, or maybe it does, but then Obsidian needs to clarify on how it works, because the perk description simply says " you gain +5% critical hit chance and enemies suffer 25% crit chance failure." No, this is not true, Obsidian. The way this perk and other similar perks like Laser Commander are implemented is different from the Finesse perk or the 1st Recon beret, because Light Touch doesn't increase your base critical, nor does it decrease the enemy's base critical, it's a flat modifier and it COMPLETELY ignores the weapon critical multiplier. So if a weapon has a 5x crit chance, the 5% bonus critical added by Light Touch is NOT multiplied by 5 and the enemy penalty is NOT multiplied by the enemy's weapon's critical chance. I don't know if this is intentional or not, but don't you think this is information worth mentioning, Obsidian?
Ok, so here's the crit chance formula used by FNV fyi:
base crit chance * weapon crit multiplier + crit chance multiplier + vats crit multiplier
So a player with 10 luck, Finesse and Light Touch will have the following critical chance in Vats using a fully repaired Ratslayer (5x multiplier)
10 luck + 5 real base critical bonus added by Finesse perk = 15
15 * 5 weapon multiplier = 75
75 + crit modifier of 5% added by Light Touch perk = 80
80 + 5% crit modifier added by VATS = 85 %
So this Light Touch perk is TOTAL CRAP! If you use Finesse and Boone's beret instead, you actually get 100% crit chance in VATS:
10 luck+5 Finesse+5 beret=20 crit chance multiplied by 5x weapon critical multiplier=100%+5% vars bonus=105% crit chance overall, but it's obviously capped at 100% per cent, so it's 100% critical. Now I would really like to know if it's a bug or intentional behaviour.
Now regarding the enemy crit chance penalty applied by Light Touch:
Assume an enemy has 15% crit chance and is wielding a weapon with 2x crit multiplier. So they have 30% crit chance minus 25 penalty, means they STILL have 5% chance to hit you. Must update the info on Fallout Wiki, it's wrong there
