Hehe a new game yeah that's what i did ditching my level 42 lol..
Good idea on the Champion.. maybe next update. Ah the items, gave me headaches it wasn't loading properly because i had to swap them order... what gives.
You can use already existing icons for your new items, find a nice icon for your new item and use it's name tag "image=HeroItem_Addon_Ring03.png" which is "money lender ring".
Well here are the stats of new items
Destroyer Boots: +5 Intellect +25 Mana +1500 Leadership +5% all resist
Ancient Ring: +500 Leadership<br>[s]-10% Leadership requirement of all 5th level units<br>[s]+1 Morale to all 5th level units
Overlord Ring: +3 Attack and Defense to Demons and Undead +5 Attack and Defense to the Warriors of Darkness +6 Intellect -10% Leadership requirements for Undead and Demons -2 Morale to all other creatures in your own army
Rainbow Ring: +2 Attack, Defense and Intellect +5 to Mana and Rage +500 Leadership +2 Morale to all Humans, Dwarves, Elves, Orcs, Neutrals and Lizards +10% Chance of Critical Hit of all Humans, Dwarves, Elves, Orcs, Neutrals and Lizards
Edit
Fatt: the morale is so players gets replayability on trying out new strategies with units they usually never use together.
exp system value are higher in limit, +45 means it's now 50 maximum HP for a unit but i doubt it will go that much, random. Berserk, haven't thought of it but then i could go on and add all the spells, no end on it hehe.
Which unit are too strong?, i suppose some are... extreme

gotta think twice before taking on those.
