/shurg Can't say I've found it this way, but I'm pretty used both to DnD mechanics generally, and Larian's approach to encounter design in specific. (I've so far had exactly one combat game over, because I was dumb and let Ragzlin get into the rafters and chuck javelins at me for like 20 damage a pop.)

Positioning matters, your environment is something to be used to your advantage, abilities that boost your accuracy are very powerful, and different enemies have different strengths and weaknesses. /shurg Hard to give much specific advice, because different encounters and party compositions demand different tactics and threat assessment.
