em not experienced enough nut i will try my best...
first comes attributes
by giving points to ur attributes u gain some kind of powers or perhaps it would be better to say that ur powers increases..
by giving points to ur strength ur strength increases and u can equip ur warrior with high quality stuff
by giving points to ur vitality ur maximum health increases...
by giving health to ur agility..i guess ur maximum spirit increases
same goes for dexterity and intelligence
now comes skills
by giving points to ur attack stance...the damage that ur hero causes to enemy increases...it is not affected by the enemies defense....
by giving points to defense stance...the damage that the enemy gives u is decreased and it is also not affected by the enemies attack stance
by giving points to ur charge stance ur hero can attack with much power in the first round compared to the others
by giving points to ur mercenary...each point allows u to command one more mercenary(in my opinion it is the most important one)
now come equips
there r many type of equips like gloves,armor,weapon etc
to equip any kind of equipment....ur tier should be equal to the equipment's tier...
if equipment's level is 16 and u r at level 14...u cannot equip it...same goes for every tier....to equip items of lvl 6,16,26,36,46,56 ur hero should be at 5,15,25,35,45,55 respectively...otherwise u wont be able to equip it..
u can but equipment from auction or from shops in different provinces..
