Well now I will explain you new game systems on what I am currently working:
FIRST: You can switch if you want sword or hammer, only that two items, but when you change them you will get new spells, for sword you will have one spell pack, for hammer second spell pack, with shield you will have two defensive spells, and you will have one passive spell that is colection of many little spells.
In inventory you will have 5 items: weapon, one trinker, armor, helmet and probably boots.
All items will have custom effects,, active and passive:
for excample hammer fist have active item spell final judgement.
Trinket will heal you, etc.
New things will also be talent tree and upgradeable items, when ever you kill evemy unit u will gain souls(gold), soul gain is based
on killed unit level, that soul can upgrade your items level, and can be spent to upgrade talent tree, for excample with talent tree you can upgrade custom passive
spell: survival instict, that will give you bonus armor, regeneration, evasion chance when you are on low hp.
Well that are some new things on what I am currently workings, also I am planning to add two more bosses, valkire and another boss in one plague(new) are.
