@AlexNeb it's rng based, the more stars it has the rarer the drop
@Haroutx in game click on the cog/gear next to S1 / S2 and there'll be a disable music option
@Sak there are a lot of ways outside of levels and natural refills to gain energy which drastically cut down that set time. Level 140 is much harder to achieve compared to 50k puzzles because exp needed vastly outscales xp gain until the exp needed stops increasing. Xp gain increases by about 22-25% per level for me atm, xp required is increasing by 60%. Only a total of 15 people in game on our servers have reached 140
Strength is required to equip items, not number of slots, and it depends on what you want by best, if you want to survive longest sword is best, most damage would be mage and gunner for crits
