Sadly it is hard. If your target is at Range you holding a torch does not help, also you cant use a Two handed weapon holding a torch, also, Cantrips cost one action and the light is stationary where you enemy is not. So when your getting shot by arrows your trying to light them up and follow them with light and not shooting back.
I find this VERY significant and using a non dark vision class, in my mind will GIMP you. The good news is Gale has a dark vision spell,,,but again that takes up a spell slot....
I am not sure you guys are noticing the "hindered by shadows" reduction to hit EVEN IF THERE ARE TORCHES. The fighter (non dark vision was like 27 percent hit) my Drow had like 67 percent chance to hit.. The DROW got a bonus "hit from the shadow" GUYS that is a HUGE DIFFERENCE
Sounds like , from these responses, people have not really been paying attention to this or noticed it.
Oh I've definitely noticed it. I personally have played around a lot with the light system in this game, using torches in off hand, dropping candles, using light cast on weapons, light cast on stationary targets, fighting in fire, fighting with fire dipped weapons.
Its a huge issue, but the fault lies in the implementation of the light system, not in darkvision as a character feature. I have had combat where, if the light was working as it was supposed to, the character with darkvision should have had no extra advantage at all, but they still were, not because that feature is broken, but because the party and enemies were still incorrectly being labelled as being in shadows, despite the area being lit up,
because the light system does not work properly.
