Now that'd make Eviscerate deal some serious damage with the right weapon, right? Is Eviscerate a game-changer? The one-turn cooldown looks tasty. What's the typical damage for optimal 120-130+ pneumatic gloves?
Eviscerate is not a game changer. First of all, knives have it worse in terms of creating bleeding wounds on an enemy than do combat gloves. First of all, they have require 2-3 AP more per strike, and second, they have 25% chance per strike instead of 35% of bladed glove. Meaning that you create bleeding wounds slower. Also it means that by the time you have enough wounds on an enemy to make Eviscerate do good damage, he is already pretty close to death. Maybe some bosses are exception to this, but it is true in 95% of your playtime. It's not bad, but on my knife user that i finished the game with i skipped it entirely and didn't regret for a moment.
With robots, why not have an electricity melee weapon in one hand for those filthy creatures? It won't stun, but the armor resist question becomes pretty moot.
Electrical damage is very small part of your total damage. It deals relatively small amount of damage in the first place and doesn't get increases from your skills, strength and buffs like Taste for Blood. So electrical damage on your knife/glove is not a good solution for robots (Expose Weakness is).
Too bad bladed armor doesn't proc on sledgehammers, ha.
If you are talking about bleed damage than it would be useless anyway since sledg user spends usually 1-2 strikes on a single target anyway. If you are talking about getting Taste for Blood buff than you can get it anyway since you get 1 stack from killing someone with melee attack. I usually take it for all my sledg builds.
May it be the case that there are very few Melee weapon types and none are too useful? Just asking.
Properly built unarmed character is in the top tier along with smg and sniper rifle. Sledgehammer is a solid weapon, on par with things like assault rifles. Knives do struggle compared to the rest of the melee, since they are watered down version of unarmed in a lot of ways.
