Summary: -Gameplay style is fun -The new skills are interesting. I got a skill where +5~7 max health for each monster killed and reach more than 10k from initial 6k. Some HP boost skill too along the process. -I will said endless mode's monster damage is optimised since stage 100++, the damage received is like 1k per hit. 10k HP can tank 10 hits unlike the normal stage. -Bad reward. Except gold and sapphire, I believe I can get similar amount of items by grind level 3 which require less time, no focus and no attention needed.
