[Thunder] as a derivative element of the "Sun" power, is a fairly common spirit rune, just like light, earth, wind, water, and fire. Additionally, manipulating elements has always been a crucial part of mysticism in the supernatural systems of past eras. Therefore, there are quite a number of arcane techniques for [Thunder]. Shard unexpectedly saw a list of 50 arcane techniques all at once in the Black Raven Library, with a maximum price limit of 200 pounds.
However, in the end, Shard didn't buy anything. He plans to compare them with the arcane techniques from the Academy Library. Even though the [Thunder] spirit rune doesn't particularly fit with his current Circle Sorcerer system, given the powerful attack capabilities of [Thunder] arcane techniques, Shard is keen to associate the spirit rune with several additional arcane techniques. His energy is limited, so he must carefully consider what to choose.
