As an experienced player who spent several years on the first Ikarus server before its closure and continues to play on the new Foenix server, I want to share my best practices. If you, like me, prefer magic classes, then I recommend using the following keyboard shortcuts: assign «ice claw» to key 2, «frost bomb» to F2, and «ice squall» to key 5. 

Additionally, on key 1, set «taming» to level 3, «fire fang», and on F3 you will have «fire bomb», while on 4 - «lightning» (or «Thunderstorm»). I have thoroughly tested this macro, but keep in mind that it is better not to change the delay between beats. If you click too fast, the game may not recognize your actions and this will lead to crashes. With this scenario, you can easily cope with medium-stat mobs, and the weak ones simply won't have time to withstand the «volley».
