The 5th raid is quite ridiculous I couldn't scratch the first 3 boss with all Hero level 350. Do I really have to beat that dungeon before I can soft reset? If so I feel heavy for the newer players who has to spend a week just to do the first soft reset.
When a wave of enemy warp in, the game is frozen for a short time and negate the radar from detecting items making it unknown where to find the items that is dropped by the enemy.
