I've been seeing a lot of complaints about how the combat system and how it needs a 'Let Me Solo Her' level player to beat a goblin.
So here is my Ironman defeat-proof build. Means no cheat and no save edit. First consider taking at least 12 achievement points for stats, skills, gold and food (then magic and clothes).
The combat revolves around Tempo attack, Slide and Fade-Away.
Forget low attack because you also take damage. Tempo attack has parry and dodge properties and more agile you are the better (hence thief class)
Slide will smash them to the ground if you are agile enough. You slide into their feet, they fall down, you stand up and get couple of low attacks before they stand up, where you slide into them again. But since it needs high agility it usually is only usefull at late game where you get all the items and perks.
Starting stats would be 4 charisma (+1 with perks so it's 5 and you can get food from dryad). 3 magic (+1 with perks so you can get exp in spider dungeon and smooth golem encounters). 4 on perception (+1 with perks and +2 on surveyor). Rest goes into 3 main stats.
Edit: someone tell me how to get dullahan companion.
