Before I say anything: I gave this 4 stars(3.5 for current playability and 0.5-1star extra for potential) Best combo I have found is: Zombie Knight(Special is an AOE killing field) and nature set (Nature Sword, Rose Ring and Sacred Leaf) with a combo of 100% stun, 10sp per critical and the double heal of the Sacred Leaf. With this combo each level I would advise to put put 5 or 10 stat points into Agility (every 5 points = 1% crit rate. good for sp recovery) and 5 or 10 into Intelligence(every point increases damage of the Zombie Knight special). The rest of your stat points should go to Vitality, because, this build just uses the 15% Life Steal from the Nature Sword, not really the sword itself.
Very good game, I have rated 4 stars because of potential. Needs a bit of polish, but, from reading your page, this is a learning curve for you so I'm very impressed. I really like that the towers upgrade costs are scaled by total tower lvl and not by individual skill.
My thoughts on Mekav's question: the number shown for the protection stat is not actually a percentage, just a value used in the calculation to determine damage mitigated. secondly used in the calculation to see if you are critically hit. my apologies, just noticed my (probably incorrect) ramble.
I have a lvl 29 priest and I'm getting 0.33% exp for grinding a lvl 30 mob, is this amount correct? I'm not complaining, just want to see if its normal, great game btw.
