I am getting ready to do a hard run; was wondering if it would hinder my capabilities if I went straight for maxing my characters main stat,(str,dex,etc,)? As well as go straight to +5 in their main skills? Mainly for the rogue and the ranger.
The most you can assign to dex/str/int is 15. You don't need to max the remainder to be effective. In fact, you shouldn't up your speed (initial AP and AP recovered per turn) and perception (initial AP) unless you have the constitution (max AP you can hold) to support it.
You can max out (full 5) 3 talents in the game with some points left over for flavour (assuming max level 20).
No need to max out anything. This isnt a game made for focused maxed out builds. Its made for jack of all trades, which means that diversity in skills is very valuable and useful. If that wasnt clear anyway, just by looking at the mechanics and systems.
Hard mode isnt really hard. Its just a cheap quick trick.
Dont bother.
Wait for my proper hard mode and buy boxes and boxes of tissues in the meantime.
