This is to prevent save scumming. (save/reload untill even a 1% becomes a hit)

When you move your guy into a enemy's line of sight (and placing them into yours) the game descides if it will hit or not. if you have a 92% chance to hit guy 1, and 26% to hit guy 2, then the game calculates it on your spesific turn. Meaning both can and will always miss, no matter how much you savescum.  

If you were to use an ability however, it will be calculated differently. i assume moving into another possition will also make the game reroll your chances. It does not, however, descide at the start of your turn if your guy will be allowed to hit anything at all.  

sure you know this now, but there are combos for each secondary weapon type. goodfist are for gauntlets, claws and armblades
