In these sketches by the designers of
Phantasy Star IV, we see some practice and reference drawings for an early version of Rune Walsh, when he wore a turtleneck instead of the white trimmed collar used in the game. The bottom right is perhaps the most interesting, as it shows Rune conjuring a ball of fire. This may be either the Foi tech or Flaeli skill. It is rare to see the effect of magic in artwork like this, especially without it being directed at a monster or comrade.
