Using enery max equip, i spamed lightning storm at demon spawn, and cleared the stage in few seconds. I dont see reason to use another atack skill, because lightning storm is to powerfull, good damage, wide range, and stun effect.
I found towns wealth collapsed after i sold them hundreds of jewelry with price 4,2k per unit. Because of it, they sold it back to me with price 700 per unit. I made millions from it, but the town can't buy or sell anything with normal price anymore, they only trade with minimal price. It happens everywhere except Qubba.
I also found Diep Gat and Verdammter Platz stop their production of crude oil when i bought all of fuel they have, and the worst effect is Hara also stop their production of fuel because they lost the crude oil supply. The funny thing is, i found 56k barrel of crude oil stuck at Qubba...
I hope there will be reset stat item for main character. Also, please improve looted item stat. I had loot more than 250 items, and only found an item that have better stat than shop item
