Also the calculation formula.
In older games avoid was 2*AS + Lck. Which made evasion absurdly easy. Since DS remakes they reduces Avoid to AS + Skills. You can still get high avoid, but Skills/Terrain needed. Hit formula was changed from 2*SKL to Skl as well. 3H also had the powress skills which gave hit and evasion buffs.
Also thank god 3H moved away from proc skills to combat arts and conditional skills.
Sometimes i think Crits should be removed as well, but that would massively nerf crit based classed like Swordmasters and Berserkers, so eh.
R;B1 is a defeat boss map though iirc, no?
