Stomach

I know I have to equip a weapon that doesn´t do much damage to have a higher chance of hitting them in the stomach. But they kill me before I have a chance to do that many hits. What should I do?

Pillow
Low damage, high accuracy

The target takes half of my life in one blow.

Try asking someone else to join in with the fight (which massively reduces the target's stats) or just give this one up. Being only 15 days old, it might be worth declining this contract and focussing on stats.

Until you get at least fairly decent battle stats, you are gonna get bombed in a lot of missions. For a while missions weren't this plentiful (or weren't in the game) so most people trained for a while, so now you are seeing what happens when you try to jump right into missions without training; everyone is stronger than you.

Unless you have a need to do missions right now, ease into it, put a few months into battle stats, then start worrying about missions.

I will do that.
I´ll risk the wrath of Duke´s displeasure.

There is no displeasure, just a tiny lowering of your standing with the agent.

Hallelujah!! I am on the 'Withdrawal' mission and I have been struggling to find a way to damage each arm of my target...I finally had less than an hour left to complete it.... I'm surprised that nobody had commented on it besides me!.... but i ran across your advice about the pillow, thank you so very much!! While I couldn't find a pillow..a Book also has very high accuracy. thanks again!.
