Ancient Magic Book 10 Grade: 10 sec restores 600MP, plus 8 1 intelligence, lasting 60 sec, and cooling time 150 sec.
Ancient memory level 10: increase intelligence by 150, lasting for 20 seconds, and cooling time for 40 seconds.
It's a little difficult to fill up both because of the shortage of sp. You can choose one according to the situation.
The advantage of the magic book is that it takes a long time to return to magic and intelligence, which is very suitable for people who want to save Lan. Compared with ancient memory, it has the disadvantages of less intelligence, about half of the magic book, and longer cooling time. Cooling time 150 seconds, ancient memory can be played three times.
Therefore, according to your situation, if you are the summoner of extreme intelligence flow, it is suggested that both of them can be filled up, which is very powerful together. If you are a king of SHEN WOO or Summoning Department, according to the present situation, if it is to save Lan, then the ancient magic book is still more practical.
If you want to improve your attack power in a short time, ancient memory is a good choice.
