Hello KO4FUN Players;
You start the game with the Skill Range max limit feature, but you can turn this feature off.
It is a feature that mages will use fondly in order not to eat skill failed while novating enemies and monsters.
You can turn the Area Skill Range Limit off and on from the Effect option tab by pressing F10 in the game.
When Area Skill Range Limit is turned off "Tick", as you can see in the gif below, the skill fails while throwing nova to distant mobs.
