No seriously. Level 5, having to fight 4 slimes, without a weapon, is a gruesome grind. It just takes way too long. I'm sure there's no need to actually exterminate every ennemies specially those big groups... buuuuut i'm a loot goblin.  I loot everything and exterminate then loot anything that move >..> 

Currently got at the princess part, so maybe such an option become available after that. Buuut yeah, at least a double strike, or a flurry type attack wich hit random ennemies multiple times. Something to make it less painfull early on xD

Well, it's just a small suggestion. Not a huge issue.
