You can refer to the following runes that may be useful to the mage. The more advanced, the rarer and the more wasteful. Besides, I wrote about the effect of playing weapons.
3 # taitel +2 Mana for each enemy killed (recommended, simple and practical).
15# Haier -20% equipment requirements,
16# Io+10 vitality,
17 # Lumlum+10 energy,
18# Ko+10 agile,
19 # Farfa+10, (it seems that this is completely useless to the mage, except that it is almost powerful with good clothes).
20# Lem Lamb gets 75% extra funds,
24# Ist increases MF by 30% (that is, the probability of obtaining magic props. In other words, these are somewhat advanced runes)
33# zod Sadr never wears away, 69 (the highest rune, it should be a waste to smash ...)
